Conversion of Percents, Decimals, and Fractions FUN! FUN! FUN!

Decimals to Percents Move the decimal point 2 places to the right Example 0.63 = 63.% 1.23 = 123.% 0.02 = 2.% 0.456 = 45.6%

Percents to Decimals Move the decimal point 2 places to the left Example 64.% = 0.64 123.% = 1.23 1.5% = 0.015 45% = 0.45

Decimals to Fractions Read the decimal Example The number is the numerator The place value is the denominator Example 0.64 = 64/100 1.23 = 1 23/100 0.036 = 36/1,000 0.0006 = 6/10,000

Fractions to Decimals If the denominator is 10, 100, 1,000, 10,000 or any other multiple of ten. . . The numerator is the number The denominator is the place value position where you put the number If you can change the denominator to a multiple of ten, make the equivalent fraction with the denominator a multiple of ten. Do the same steps as above

Fractions to Decimals If the denominator is not a multiple of ten or you cannot change it easily . . FOOTBALL PILE UP! Numerator goes in the house and the denominator is outside the house

Fractions to Percents Change the fraction to a decimal Move the decimal point 2 places to the right

Percents to Fractions Write the percent as the numerator Do this only if the percent is under 99 If the percent is over 99, the hundreds place is the whole number of the fraction Write 100 as the denominator Reduce/Simplify Example 99% = 99/100 41% = 41/100 316% = 3 16/100
