Answer is 11/14 (the last choice)
Step by step
She reads 5 1/2 novels per week
We know a week is 7 days
Divide 5 1/2 by 7
Change both numbers to improper fractions
11/2 divided by 7/1
When dividing fractions you flip the divisor and multiply
11/2 x 1/7
Multiply across 11 x 1 and 2 x 7
11/14 is your answer
