Question

Ryan has a box of markers. It has 45 markers that are some shade of blue. The blue markers represent 25% of the total markers in the box. What is the total number of markers in the box?

Answer 1

Ratio time :)

25 percent of 100 = 45 of the unknown number

25/100 = 45/x

Cross multiply
25x = 4500
x = 180

180 total markers in the box
