PLEASE HELP ASAp

Sophia has a shelf that is 51 over 2 inches wide. How many notebooks can Sophia arrange on the shelf if each notebook is 3 over 2 inches thick?

38, because the number of notebooks is 51 over 2 ⋅ 3 over 2
153, because the number of notebooks is 51 over 2 ÷ 3 over 2
102, because the number of notebooks is 51 over 2 ⋅ 3 over 2
17, because the number of notebooks is 51 over 2 ÷ 3 over 2

Answer 1

The answer to this is 17

Answer 2

That would be 17.
Why?
The number of notebooks is 51/2 divided by 3/2.
(51/2)/ (3/2)= 51/2 * 2/3 = 102/6 =1717
