3. Dividing Fractions Review When dividing fractions, they do NOT need to have a common denominator. To divide two fractions, change the operation to multiply and take the reciprocal of the second fraction (flip the second fraction). Keep-Change-Change. Change Operation. Flip 2nd Fraction.

8. A group of 6 hikers are preparing for a one-week trip. All of the group’s supplies will be carried by the hikers in backpacks. The leader decided that it would be fair for each hiker to carry a backpack that is the same fraction of his weight as all the other hiker’s. In this set-up, the heaviest hiker would carry the heaviest load. The table below shows the weight of each hiker and the weight of his/her backpack. On the next slide you will complete the table by finding the missing amounts of weight by applying the same ratio as the first 2 rows. Hint: There are 16oz in 1 lb.
