What is 1 7/12 - 3/20 equal to?
I tried to do this question but I couldn't quite get the answer. For the directions of the work, its says use the least common multiple as the denominator and when I came across this one, I couldn't quite get the answer. If anyone, who knows the answer, can tell me and explain why and how to do it. Thanks!

The least common multiple of 12 and 20 is 60.

1 7/12 = 1 35/60

3/20 = 9/60

1 35/60 - 9/60 = 1 26/60 = 1 13/30
