Eloise practiced piano for 2/5 of an hour. Sarah practiced piano for 3/4 of an hour. How much longer did Sarah practice than Eloise?

21 min longer

Step-by-step explanation:

For Eloise, we need to know how much 1/5 of an hour is in min. So divide 60 by 5 and we get 12min. So 2/5 of an hour is 2x12, giving us 24 min.

For Sahrah, we need to know how much 1/4 of an hour is in min. So divide 60 by 4 and we get 15min. So 3/4 of an hour is 3x15, giving is 45 min.

now that we know how long they practiced, we find the difference by subtracting. 45-24 = 21
