18 2/9
-13 4/7
The common denominator is 63
2(7)/63 for the first fraction
9(4)/63 for the second fraction
14/63 - 36/63
you cannot subtract the 36 from 14
You have borrow one from the 18
the 18 becomes 17 + 1 or 17 +63/63
Now, your problem becomes
17 77/63
-14 36/63
can you finish from here? remember to reduce the fraction to lowest terms if needed.
