Answer 1

First one:
7.6÷7.6=0 so the answer to this one is 0.

Second one:
You first need to convert the fractions.
24/36-(9/36)×(16/36)

Remember the order of operations and start solving.
First multiply.
9/36×16/36=1/36×16/4=16/144=4/36
So now solve: 24/36-4/36= 20/36=5/9
The answer is: D.5/9

Sorry I don't really understand the third one :(

Answer 2

for the first answer it is C because to get the same number you do not have to add or subtract anything
