Lesson 14 Solving Percent Problems Pdf Percentage Interest Percent problems can be solved by writing equations. an equation uses an equal sign (= ) to show that two mathematical expressions have the same value. percents are fractions, and just like fractions, when finding a percent (or fraction, or portion) of another amount, you multiply. 2) what percent of 33.5 is 21? 4) 41% of 78 is what? 6) 58% of what is 63.4? 8) what percent of 38 is 15? 10) what is 12% of 17.5? 12) what is 59% of 14 m? 15) $73 is what percent of $125?.
Solving Percent Problems Worksheets These problems deal with quantities that are changing; that is, increasing or decreasing. if a quantity increases we have a percent increase problem and if a quantity decreases we have a percent decrease problem. If we recognize the fractional equivalent of a given percent, we may find the problem easier to work by changing the percent to a fraction instead of a decimal. Percent problems solve each problem. 1) 20 is what percent of 50? % 2) 18 is what percent of 90? % 3) 12 is what percent of 15? %.
