1. 9/10  

2. 14/15

3. 1   1 /6 or 7/6

Step-by-step explanation:

1. Change the 5, the denominator to 10.  8/10

then add to 1/10  8/10 + 1/10= 9/10

2. Change both denimnators to 15. You will then get 9/15 and 5/15.

Add them together and get 14/15

3. Change both denominators to 6 and you will get 3/6 and 4/6.

Add them together to get 7/6.

If you want to make it into a mixed fraction it would be 1 1/6 (as in one and one-sixth)
