assuming 13 and 34 are meant to be 1/3 and 3/4
1/3 x 4/4 = 4/12
3/4 x 3/3 = 9/12
4/12 + 9/12 = 13/12
or 1 + 1/12
78 + 34 is 112, which is an integer, not a fraction.
78 + 34 is 112, which is an integer, not a fraction.
56 + 34 = 90 is an integer, not a fraction.
-13 + 34 = 21
It is 4 1/34.
5420
34
It is -34 + v.
It is 3/13.
34 + 61 - 64 + 18 = 13
13/4 = 7/4.
It is -34 + v.
