Question

A collecter has 120 movie posters and 100 band posters she wants to sell 24 movie posters but still have her poster collection maintain the same ratio 120:100 if she sells 24 movie posters how many band posters should she sell explain

Answer 1

Explanation:

Calculation is done as follows:

Number of movie posters remaining = 120 - 24 = 96

Number of band posters remaining= x

120:100 = 96:x

x = 80

100-x = 100 - 80 = 20

Therefore, she should sell about 20 band posters for her to maintain the same ratio of the movie posters to the band posters.
