Mark I's Scribe Post


Today in class we corrected our homework. Our homework was to convert fraction's, decimal's, percent's and ratio's to fraction's, decimal's, percent's and ratio's. There are 12 in total, 3 for each topic.
Fraction's:
1. Fraction-Decimal: To convert a fraction to a decimal, you have to divide the numerator by the denominator.

2. Fraction-Percent: To convert a fraction to a percent, you have to divide the numerator by the denominator and multiply the answer by 100.

3. Fraction-Ratio: To convert a fraction to a ratio, you have to know that there are 2 parts to a ratio. The 1st part is the numerator and the 2nd part is the denominator-the numerator.
1. 4/5 4-:-5=0.80
2. 4/5 4-:-5=0.80 .80x100=80%
3. 4/5 5-4=1 4:1
Decimal's:
1. Decimal-Fraction: To convert a decimal to a fraction you put the decimal number over 100.

2. Decimal-Percent: To convert a decimal to a percent you have to multiply the decimal by 100.

3. Decimal-Ratio: To convert a decimal to a ratio, you 1st have to convert the decimal to a fraction. Then you put the numerator as the 1st part and the number you get when you - the denominator from the numerator as the 2nd part.
1. .3 30/100=15/50=3/10
2. .3 .3x100=30%
3. .3 3/10 3-10=7 3:7
Percent's:

1. Percent-Fraction: To convert a percent to a fraction, you have to just have to put the percent over 100 to get the fraction.

2. Percent-Decimal: To convert a percent to a decimal, you have to divide the the percent by 100.

3. Percent-Ratio: To convert a percent to a ratio, you have to convert the percent to a fraction by putting the percent over 100.Then you put the numerator as the 1st part and the 2nd part will be the answer of the denominator-the numerator.
1. 57% 57/100
2. 57% 57-:-100=.57
3. 57% 57/100 100-57=43 57:43
Ratio's:

1. Ratio-Fraction: To convert a ratio to a fraction, you put the 1st part of the ratio the numerator and add the numerator and the denominator and put is as the denominator.
2. Ratio-Decimal: To convert a ratio to a decimal, you have to 1st convert the ratio to a fraction by putting the 1st part of the ratio the numerator and the answer of the denominator-the numerator, put it as the denominator. Then you divide the numerator by the denominator.

3. Ratio-Percent: To convert a ratio to a percent, you first have to convert the ratio to a fraction by putting the 1st part as the numerator and putting the answer of the denominator-the numerator as the denominator. After you divide the numerator by the denominator and multiply the answer by 100.
1. 2:4 2/6
2:4 2/6 2-:-6=.33
3. 2:4 2/6 2-:-6=.33 .33x100=33.3
Homework:

Equivalents The Assignment

1. Make 4 different fractions using the digits below. You may only use each digit once. Convert these 4 fractions into decimals, percents and ratios.
1, 2, 3, 4, 5, 6, 7, 8, 9
2. Make 4 different decimal using the digits below. You may only use each digit once. Convert these 4 decimals into fractions, percents and ratios. (Do not use the decimals from the question above).
1, 2, 3, 4, 5, 6, 7, 8, 9
3. Make 4 different percents using the digits below. You may only use each digit once. Convert these 4 percents into fractions, decimals and ratios. (Do not use the fractions and decimals from the questions above).
1, 2, 3, 4, 5, 6, 7, 8, 9
4. Make 4 different ratios using the digits below. You may only use each digit once. Convert these 4 ratios into fractions, decimals and percents. (Do not use the fractions and decimals or percents from the questions above).
1, 2, 3, 4, 5, 6, 7, 8, 9

Remember only to use the digit only once and to make it into a fraction, decimal, percent and ratio also!
Answer these questions:
Convert 6:14 to a percent
Convert 36% to a decimal
Convert 78/100 to a ratio
Convert .23 to a fraction
