To divide fractions, you multiply by the reciprocal. For example:

2/3 by 3/5 would be 3/2*3/5=9/10

and so on. You will want to simplify your answer if it needs it.

7/12 by 2/3 is 21/24 which goes to (7/8)
3 1/2 by 3/4 is 28/6 which goes to (4 and 2/3)

Flip the divisor and multiply. Don't forget to divide common factors out of the numerator and denominator of the result.

For the estimate, ask yourself "what is 5 x2 ?"
