Question

Macy finished a job in 3/4 hours . James finished it in 4/5 of the time Macy took. How Long did James take to finish the job?

Answer 1

3/4 hours is equal to (60 minutes divided by 4) times three. [15*3 = 45] 
Macy finished in 45 minutes. Now we have to find 4/5 of 45. So (45 divided by 5) times 4. [9*4 = 36] 
See the pattern? So the answer for 45 minutes divided by 4/5 is 36 minutes.

Answer 2

36 minutes is the correct answer
