Question

Jake can carry `6 1/4` pounds of wood in from the barn. His father can carry `1 5/7` times much as Jake. How many pounds can Jake's father carry?

Answer 1

`10 5/7` pounds

Explanation:

The first thing is to decide what operation you need to do. Think of an easy equivalent example. If Jake can carry 2 pounds and his father can carry 3 times as much. The father can carry `2 xx3 = 6`

The operation was multiplication:

In this example, it is multiplication of fractions.

`6 1/4 xx 1 5/7" "larr` change to improper fractions

`=25/cancel4 xxcancel12^3/7" "larr` cancel where possible

`=75/7" "larr` multiply straight across, top and bottom

`=10 5/7" "larr` change to a mixed fraction
