Fraction to Decimal 2. Divide 1 2 EX 1) = 1. Make denominator a power of 10. OR X X 5 10 ?5 5 Put numerator behind decimal at appropriate place value = 0.5 = EX 2) 1 8 ● ● 0 1 8 2 00 2 16 4 0 5 0 3 = 3.5 Mixed numbers work the same way – whole number stays whole number 1 8 15 1 8 =.125 15

3
20 100 x 20 Fraction to Percent 1.Make an equivalent fraction with 100 as the denominator EX 3) EX 4) 1 5 = =20 % 2. Any fraction with a denominator of 100 can be written with the numerator as a percent. X X 20 100 x 5 16 = 3. Use solve proportions when denominator cannot be multiplied by a whole number to make an equivalent fraction with 100 as the denominator. Cross multiply and divide 5 x 100 ÷ 16 3 48 2 1 16 4 500 16 0 4 3 1 4 1 % Leave as fraction or make decimal 1 % 3.25 3 3 3 Mixed number – Whole number goes first

4
Percent to Fraction 1.Put percent over 100 2.Simplify EX 5) EX 6) 50 %= 50 100 = 5 10 = 1 2 430 %= 430 100 = 43 10 = 3 4
