Question

A collector has 180 movie posters and 120 band posters she always to sell 27 movie posters but still have the same ratio of 180:120 how many band posters does she sell

Answer 1

Answer: 18 band posters

Step-by-step explanation: the ratio will always be 180:120 or 3/2

180-27 = 153 so if she sells 27 posters and the ratio is 3/2 then the amount of band posters left would be 153 divided by 3/2 = 153/1 * 2/3 = 102 so if there are 102 posters left and she had 180 then you would subtract them 120 - 102 = 18
