Answer:
I can't give you the answers because I don't know, but I know that you need to make the denominator in each faction equal. So for the first problem you would have to make 4 and 7 the same number using either multiplication or division.
1. 71/28 or 2 15/28
2. 27/10 or 2 7/10
3. 5/6
4. 5/4 or 1 1/4
5. 25/12 or 2 1/12
Hopefully this helps! Did most of them on math-way...
