Question

Maggie is participating in her school reading challenge. She read 18 of the total 25 books. What percent of books did she read?

Answer 1

Set up a system of equations and solve.

$\frac{18}{25} = \frac{x}{100}$

25x = 18(100)

25x = 1800

25÷25x = 1800÷25

x = 72

Maggie has read 72% of books.
