Objective  SWBAT use equations to solve percent problems

Percent- means ‘per one hundred’ or divided by 100. How many cents are there in a dollar?

Section 7.2 “Percents and Proportions” You can represent “a is p percent of b” using the proportion You can represent “a is p percent of b” using the proportion In this equation, b is the whole number and a is the number that is compared to the base. will equal the percent. Remember this?

Try It Out… What percent of 25 is 17? Write a proportion where 25 is the base and 17 is a part of the base. Percent proportion Substitute and then cross multiply 17 is 68% of 25

Section 7.4 “The Percent Equation” You can represent “a is p percent of b” using the equation You can represent “a is p percent of b” using the equation where a is a part of the base b and p%, is the percent. where a is a part of the base b and p%, is the percent. partispercentofwhole

Try It Out… What number is 11% of 88? Use an equation where 11% is the percent and 88 is the base. Percent equation Substitute and then solve the equation 9.68 is 11% of 88

Try It Out… 30 is 12.5% of what number? Use an equation where 12.5% is the percent and 30 is a part of the base. Percent equation Substitute and then solve the equation 30 is 12.5% of 240

Try It Out… What percent of 90 is 72? Write a proportion where 90 is the base and 72 is a part of the base. 72 is 80% of 90 Percent equation Substitute and then solve the equation

Methods for Solving Percent Problems… Types of Percent Problems (1) Find a percentWhat percent of 136 is 51? (2) Find a part of a baseWhat number is 15% of 88? (3) Find a base20 is 12.5% of what number? Proportion Equation or
