### Fractions, Decimals, and Percents

• You can write a percent in different forms, such as a ratio, a fraction, and a decimal.
• The word “of” signals multiplication, and the number that follows “of” is the denominator or divisor.
• To convert a fraction to a decimal, divide the numerator by the denominator.
• To convert a decimal to a fraction, place the digits over their corresponding place value, then simplify if necessary. For example: 0.3 = 3/10, 0.03 = 3/100, 0.003 = 3/1000.
• To convert a decimal to a percent, move the decimal to the right two places.

## Write 58% as a fraction.

• 58% = [58/100] =

## Write 90% as a fraction

• 90% = [90/100] =

## Write 75% as a fraction

• 75% = [75/100] =

## Write [4/25] as a percent.

• [(4 ×4)/(25 ×4)] =
• [16/100] =

## Write [7/20] as a percent.

• [(7 ×5)/(20 ×5)] =
• [35/100] =

• 0.4 ×100% =

• 0.09 ×100% =

## Write 30% as a decimal and a fraction.

• As a decimal: 30% ÷ 100% =
• 0.3
• As a fraction: 30% = [30/100] =

## Write [6/15] as a decimal and a percent.

• As a decimal: 15|  6.0   =
• 0.4
• As a percent: 0.4 ×100% =

## Write 43% as a fraction and a decimal.

• As a fraction: 43% = [43/100]

## A group of adults were surveyed for their relationship status. 20 were single, 7 were in an open relationship, and 28 were in a closed relationship. c) What decimal, to the nearest hundredth, of adults were in an open relationship?

• c)[7 open/55 total] =
• 55|  7.000   =

## A group of adults were surveyed for their relationship status. 20 were single, 7 were in an open relationship, and 28 were in a closed relationship. What percent, to the nearest ones place, of adults were in a closed relationship?

• d)[28 closed/55 total] =
• 55|  28.00   =
• 0.51 ×100% =
