So 0.017 = 0.017 x 100%. = 1.7% The principle of 100 applies to fractions as well. Suppose we want to convert into a percent. Again to convert into a percent we multiply the number by 100%. So we need to multiply the fraction by 100 and usually we write the percent as a mixed number. Principle of 100 rules: There are only two rules to remember when doing percent conversions, you will either multiply or divide by 100. To convert a fraction or decimal into a percent, we multiply the number by 100% and simplify. To convert a percent into a fraction or decimal we remove the % and divide by 100 and simplify. A good rule of thumb is if you see the symbol %, you will be dividing by 100. If you don’t see the symbol and you want to put one on, then you need to multiply by 100. Try the following conversions with your instructor. Remember to use the principle of 100. Example 1: Convert 55% into a fraction Example 2: Convert 7.4% into a decimal. in lowest terms. Example 3: Convert 0.267 into a percent. Example 4: Convert into a percent. (Write your percent as a mixed number.)
