Exercise 10 Page 134

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

Equation: p = 1.35* 64
Solution: p = 86.4

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 135 % of 64, which means that we want to find the part. Let p represent the part. p = 135 % * 64 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: 1.35

We got that 135 % is equal to 1.35. p = 135 % * 64 [0.3em] ↓ [0.3em] p = 1.35 * 64 Finally, let's solve the equation for p.

p = 1.35 * 64
p = 86.4

We found that p= 86.4 is a solution to the equation. This means that 135 % of 64 is equal to 86.4.
