Question 890365
Evaluate the expression:

Problem: 8 3/7 - 2 1/2

Work so far: 59 / 7 - 5/2

? /14 - ?/14
-------------
You're doing the right things.  Now you have to make changes to the NUMs to match the changes to the DENs
---
59/7 = ?/14
The DEN is 2x, so the NUM has to be 2x
= 118/14
Can you do the other one?
