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
