Answer 2

Make both into an improper fraction...
2 1/8= 17/8      2= 2/1
Now you would do 17/8 divided by 2/1, one thing though, flip the 2/1 to make it a 1/2.
Than instead of the division sign, make it into a multiplication sign! 
When you do this you should get the answer 1  1/16
Hope this helped and have a GREAT day!!
