A new section of freeway will be 8 1/2 mi long. During the first month of construction, 2 7/10 mi were built. During the second month, 3 3/5 mi were built. How many more miles were left to build?

A DVD case is 9/16 in. Thick. How many of these cases will fit on a shelf that is 1 1/2 ft wide?

Change everything to inches and then divide the shelf width by 9/16
Remember when dividing fractions you multiply the the reciprocal.
You will multiply the shelf by 16/9
