### Danny's scribe

Anyway, all we did in lass was a test.

To me it was rather easy. To pass it you'd just need to be in class.

There were only three questions on this test.

The first was to make a chart.

You would have to make an eqquivalent for each into Ratio,decimal,percent, and fraction

It would look sort of like this

0.29 95.34% 5:6 3/4

0.29 0.9534 0.4545 0.75

29/100 95.34/100 45.45/100 75/100

29% 95.34% 45.45% 75%

29:71 95.34:4.66 5:6 3:1

You also had to put this on a number line.

The next question was for you to find the average of five numbers without using you calculator.It has to equal ten.

To do this you should add them all up, then divide by five. 6+6+8+14+14=48/5=9.?

That's all you need to know for sure. That it;s less than ten

The last question you had to do was about ratios. You had 7 oranges out of 12 pieces of fruit.

Find six equivalent ratios. You had to put them in word form and numerical form.

Oh ya we also did a science test.

The next scribe is BRETT

### Blog Etiquette

I will show you just how many countries are showing up,

Wow. This is why I would like to mention a few points. I love your enthusiasm. I want it to continue.

On every timeline, make sure you have the two ends lines and a middle line. Ex

Whenever you put data on your timeline use a different colour then the same colour as the timeline is. Ex.

•Decimal:

•Ratio:

*For ratios you can convert into fractions or decimals. Just make sure you leave the 'Raw*Data'

*on the timeline. ( I used decimals >>>>)*

Ex. : 1+7=8 18 = 0.125 x 100 = 12.5

### Math Pretest Equivalents

Convert the following values so that you can place them on the number line below. Show all your work.

0.175 | 55% | 3:10 | 15/51 | 9:3 |

How could you determine whether the average of these numbers is greater than 10 or less than 10 without actually computing the average. Explain how you decided the average was more than or less than 10.

**In Wendsday's class Mr.H gave us a chart of decimals, fractions, ratios, and percents.With those decimals, fractions, ratios, and percents we were asked to place them on a number line in order. To do that you had to convert all of the decimals, percents, fractions, and ratios into either percents, fractions, decimals, or ratios. The easiest one to place in order would be percents.**

**I am going to convert the decimals, percents, fractions, and ratios shown in the chart above into percents so it makes it possible to put them in order.**

**50%= 50%**

**0.7= 0.7 x 100= 77%**

**17/40= 17 divided by 40 x 100= 42.5%**

**29/47= 29 divided by 47 x 100 = 61.7%**

**3/4= 3 diveded by 4 x 100= 75%**

**9/10 = 9 divided by 10 x 100= 90%**

**o.484= 0.484 x 100= 48.4%**

**66:34= 66/100= 66 divided by 100= 0.66 x 100= 66%**

**2:3= 2/5= 2 divided bye 5= o.4 x 100= 40%**

**7:5= 7/12= 7 divided by 12= 0.5833333 x 100= 58.3%**

**0.82= 82 x 100= 82%**

**80/108= 80 divided by 108= 0.7407407 x 100= 74%**

**5/6= 5 divided by 6= 0.8333333 x 100= 83.3%**

**95.8%= 95.8%**

**17/200= 17 divided by 200= o.085 x 100= 8.5%**

**77:44= 77/121= 77 divided by 121= 0.6363636 x 100= 63.6**

**37.5%= 37.5%**

**0.08= 0.08 x 100= 8%**

**80:30= 80/110= 80 divided by 110= 0.7272727 x 100= 72.7%**

**18/92= 18 divided bye 92= o.1956521 x 100= 19.5%**

**After all of the decimals, ratios, and fractions have been converted into percents they should be put into order.**

**8%,8.5%,19.5%,37.5%,40%,42.5%,48.4%,50%,58.3%,61.7%,63.6%,66%,72.7%,74%,75%,77%,82%,83.3%,90%,95.8%**

**The percents can now be placed on a number line. Like the number line shown below.**

**On the bottom of the number line will be the raw values of the percents above.**

### NOVEMBER 17, scribe

In Friday's class Mr.Hanley talked about Fractions, Decimals, and Percents. We had to explain different parts of the Fraction, Decimals, and Percents.

**Fractions** :

- NUMERATOR : part of the whole *

- DENOMINATOR : the whole number *

- A decimal x 100 = a fraction

- Improper, Mixed, Proper fractions *

- Can be used to show probability

- Can be simplified- Part of a whole *

**Decimals** :

- represents a real number

- Place Value : 10th, 100th, 1000th etc. *

- part of a whole number *

- can be converted to a fraction or a decimal

- whole number and a decimal

**Percent** :

- part of 100% *

- an average is the percent

- part of a whole number *

- can be converted into a fraction or decimal

**HOMEWORK** : make up a definition for the ones that have a star beside them .

### // CHARMAINE'S SCRIBE POST .

Today in class we learned about **ratios.**

First, we did a quiz on equivalents then Mr. Hanly gave each of us 5 pieces of blocks ( 2 sets of color ) .

**Remember***

** To get the fraction of ratio, you add the two numbers to get the denominator. The left side number of the ratio is always the numerator.

**Remember***

*RATIO :*part to part

*FRACTION :*part to whole**//. HOMEWORK !**

**----**

**Fraction:**

**Decimal:**

**Percent:**

**CORRECT THE**

*WRONG*ANSWERS TO EACH QUESTIONS [ post it as a comment ]**7:30**= 7/30 0.180 17.9%

### Scribe Post For Nov.15

**Yesterday, we handed in the Square Root unit.**

**We also started a new unit called equivalents.**

**To start off the unit, we were handed a bag of cards. Each bag of cards had cards of percents, fractions, decimals and picture fractions. You had to put each card in a row that was similar and a column that was similar.**

**When you when do, a teacher came and saw what you had done. When you had it correct, you put what you what you did on a piece of paper that was handed out at the beginning of the activity.**

**On that piece of paper, you put what you did on the table on to the paper.On the paper, there was one extra column and an extra row. The extra column and row were where you justify you reasoning for putting what you put in that column or row.**

**Sorry for the wait.**

The next scribe is.........

**Today during our math class we did a one question quiz.**

**We also did a review from yesterday.**

**Here is a question:**

**We did a short cut on how to find the DENOMINATOR of the perfect squares.**

**This is how we did it:**

**1. Find the two perfect squares that the square root is between.**

**2. Subtract the small perfect square from the larger perfect square.**

**3. The answer is the denominator.**

Math Cumulative Test

1. Question,

Add som chips to cup 2 so that the probability of drawing a red chip out of cup 2 is greater than the probability of drawing a red chip out of cup 1?

you have to add 4 chips to cup 2, so the probability of getting a read is 4/7 which is 57.14. which is greater than 50.

2.Question,

Michael's math test scores are given below. Can Michael do well enough on the next to raise his average to an 80? Explain your reasoning. (Each test is worth 100 points)

Answer:

60 85 70 75 80 370

--------------- = ----- = 74%

5 5

60 85 70 75 80 100 470

-------------------- = ---- = 78.3%( repeating)

6 6

Michael won't be able to raise his grade beacause even if he gets 100% on his next test he will only get 78.3%.

after the test ..

After the test we did more squares learing about the " afro's " and " mulet's "

After that we go an assignment about squares ..

We had to make all the possible squares up to 16. And draw them out on a piece of grid paper. Then glue it to another piece of paper. Then you put all the perfect square to the right and all the squares with " afro's " to the left.

That assignment is due today .. last period (:

****Answer****

**4.16.**

**REMEMBER!! it doesnt go all the way around!**

answer: ONE

**THE WHOLE NUMBER REPRESENTS HOW MANY TILES YOU USED TO MAKE THE PERFECT SQUARE AND THE DECIMALS REPRESENT THE LEFTOVERS!!**

### Michelle's Scribe Post

**The first thing we had to do was draw as many rectangles as we could with the areas of 10, 16 and 36 on graph paper. To get the areas, you have to multiply the width by the height.**

16:

**The second thing we did was copy down definitions for factors and perfect squares.**

Factors:

-any two or more numbers that are multiplied to make a product

Examples:

18:

1*18

2*9

3*6

25:

5*5

9:

3*3

The 25 and 9 have one thing in common with the factors. Their factors are

multiplied by themselves. example 16: 4*4

Perfect Squares:

-a square that has the same whole number for all sides

Example:**The last thing we did was make charts on factors, exponents and areas from 1*1 to 30*30. The 2 on the exponents means squared or the number is multiplied by itself one time. ****example: **

Here are the charts:

**Homework:**

Answer the following question:

Which one of these numbers are a perfect square?*6, 8, 9 or 10*. Justify your answers.

Prove using pictures, words and numbers.*Explain why or why not the number is a perfect square.*

Answer: The number that is a perfect square is 9. This is because the only factors of 9 are 3*3.
