Subtracting fractions

These are just not that hard. One of the fractions in each problem already has the common denominator!! I'll do the first one for you.

1/2 +1/10 ~~~>10
therefore 5/10 + 1/10 = 6/10 = 3/5

Now it's your turn.

You typed, "i.ve done the best i could but aren't sure there right."

I haven't seen any of your work yet. Where did you post it?

1x2

5x5

this is soooooooooooooo BORING

Of course! I'd be happy to help you with addition and subtraction problems. Please provide me with the specific problems you would like assistance with, and I will explain step-by-step how to solve them.
