Question

A gallery owner is hanging up 444 pictures for an exhibit. She has put up 37 pictures in 9 minutes. If she continues at the same rate how many more pictures will it take her to hang the rest of the pictures? show 2 ways on how to solve this problem in a proportion

Answer 1

37 pictures in 9 minutes can be written as a ratio of 37:9.

Now 444 is divisible by 37, it's 12. So we can multiply both 37 and 9 from the ratio by 12 to find out how long will it take to hang 444 pictures:

37 * 12 : 9 * 12
444 : 108

Answer: It'll take 108 minutes (1 hour and 48 minutes) to hang 444 pictures.
