To change a decimal to percent: 1. Multiply it by 100. 2. Add the percent sign. Ex. 0.23 = 23 % 9.1 = 910 % 0.7 = 70 % 45.9 = 45.90 %
Answer as fast as you can 1. 0.99 2. 0.172 3. 0.8 4. 1.20 5. 10.30
To change a percent to decimal: 1.Divide it by 100. 2.Remove the percent sign. Ex. 34% = 0.34 5%= 0.05 1.6% = 0.016 0.6%= 0.006
To change a decimal to fraction, find the fractional equivalence of the place value. Ex. 0.7 = 7/10 0.80= 800/100 or 4/5 1.3 = 1 3/10 12.789= 12 789/1000
Try These: 1.0.4 2.0.73 3.1.2 4.0.093 5.30.97
To change a fraction to decimal, divide the numerator by the denominator. Ex. ½ = (1÷2) = 0.5 ¾ = 3÷4 = 0.75 7/10 = (7÷10) = 0.7 34/100 = (34 ÷ 100)= 0.34
Answer as fast as you can 1. 2 9 2. 4 100 3. 3 10 4. 5 20 5. 130 = 1000
Fractions, Decimals, and Percents. Percents as Decimals To write a percent as a decimal, divide by 100 and remove the percent symbol. Example 1: 63% 63.
