1 Conversions Review Name: Date: 1. Convert the following Percent s to Decimals Move the decimal two places to the LEFT. When there is no decimal in the number, it would be at the end of the number. a. 50% = b. 25% = c. 5% = d. 9% = e. 12% = f. 65% = g. 150% = h. 86% = i. 60% = j. 99% = 2. Convert the following Fractions to Decimals. Read the number out loud and use place value to help determine where the decimal should be. Use equivalent fractions (Make denominators tenths, hundredths, or thousandths, then use place value to help) a. 8 b = e = f = c. 34 g = d. 3 h =

2 3. Convert the following Decimals to Percent s. Move the decimal two places to the RIGHT, and add a percent (%) sign. a = f = b. 1.5 = c = d = e = g. 0.3 = h = i = j = 4. Convert the following Fractions to Percent s Create an equivalent fraction with the denominator 100. The numerator will be the percent. Add a percent (%) sign. Use Long division to get a decimal, and then move the decimal 2 places to the right to get a percent. Add a percent (%) sign. a. 2 e. 23 b. 46 c = d. 151 f. 6 g. 2 5 = h. 3 4 =

3 5. Convert the following Decimals to Fractions in Simplest Form. Read the number out loud and use place value to determine the denominator of the fraction. Simplify if possible If both numbers are even: Divide by 2 If either number ends in a 0 or a 5; Divide by 5. If both numbers end in a 0; Divide by 10 If the numerator ends in 25, 50, or 75: Divide by 25. a = b = c = d. 0.7 = e = f. 1.9 = g. 0.4 = h. 0.8 = 6. Convert the following Percent s to Fractions in Simplest Form. Percent means Out of 100. The number(s) in front of the percent sign will be the numerator, and the denominator will be 100. Simplify the fraction if possible. If both numbers are even: Divide by 2 If either number ends in a 0 or a 5; Divide by 5. If both numbers end in a 0; Divide by 10 If the numerator ends in 25, 50, or 75: Divide by 25. a. 9% = f. 25% = b. 40% = c. 5% = d. 15% = e. 125% = g. 50% = h. 100% = i. 40% = j. 90% =
