10. Divide
a.) 1 1/12 divided by 2 1/2

You need to turn the mixed numbers into an improper fraction.1 and 1/2 becomes13/12 and 2 and 1/2 becomes 5/2. Since you have to do the reciprocal on the denominator, you multiply 13/12 by 2/5 on the top (numerator). Then simplify your answer if needed.

b.) 8/11 divided by 4/5

Do the reciprocal on the denominator then after you do that step, you put the reciprocal on the denominator and multiply those. Simplify if it is needed, in this case, I simplified it by 4.

c.) 1 3/8 divided by 2 3/4

#### Do the reciprocal on the denominator then after you do that step, you put the reciprocal on the denominator and multiply  those.
