Exercise 6 Page 133

To solve problems that involve percent, use the percent equation.

Equation: p = 0.53* 470
Solution: p = 249.1

Practice makes perfect

Let's start by recalling that we can use the percent equation to solve problems that involve percent. Percent Equation [0.3em] part = percent * whole In this case, we are asked to find 53 % of 470, which means that we want to find the part. Let p represent the part. p = 53 % * 470 Before we can solve the equation that we got, we need to write the percent as a decimal. We can write a percent as a decimal by ignoring the percent symbol and moving the decimal point two places to the left.

percent as decimal: 0.53

We got that 53 % is equal to 0.53. p = 53 % * 470 [0.3em] ↓ [0.3em] p = 0.53 * 470 Finally, let's solve the equation for p.

p = 0.53 * 470
p = 249.1

We found that p= 249.1 is a solution to the equation. This means that 53 % of 470 is equal to 249.1.
