Exercise 5 Page 133

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

Equation: p = 0.24* 25
Solution: p = 6

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 24 % of 25, which means that we want to find the part. Let p represent the part. p = 24 % * 25 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: 0.24

We got that 24 % is equal to 0.24. p = 24 % * 25 [0.3em] ↓ [0.3em] p = 0.24 * 25 Finally, let's solve the equation for p.

p = 0.24 * 25
p = 6

We found that p= 6 is a solution to the equation. This means that 24 % of 25 is equal to 6.
