Step-by-step explanation:

This is very hard to be explained, sorry.

Answer:

The first one:   35/10

Second:   6/10

These are the answers because since you are trying to solve to get a denominator of 10, you must multiply both the to and bottom numbers by whatever you need to get the denominator to 10.  For example, for 3/5 you would multiply both the top and bottom numbers by 2, because you nned to multiply the denominator by 2 to get 10.

Answers

Answer:
