Answer:
14 11/14
Explanation:
set to improper fraction
12 4/7 - 88/7
2 3/14- 31/14
now find the GCF which if is 14
so set both equations under 14
88/7 will now be 176/14 ( u need to multiple the 7 by 2 to get 14 so you multiple 88 by two also. )
and 31/14 will stay the same
now you add 176/14 + 31/14 which is 207/14
now u simply that too
14 11/14
