Question

James bought 5 1/6pounds of grapes for $7.75. At theunit rate, how much would 3.4 pounds of grapes cost?

Answer 1

Explanation:

5 1/6 pounds of graphs are bought for $7.75, meaning 1 pound costs

`\frac{7.75\text{ dollars}}{5(1)/(6)lb}`

And we need to compute the division above.

The first step is to convert the mixed number 5 1/6 into an improper fraction.

Now, it is true that

`5(1)/(6)=5+(1)/(6)`

multiplying 5 by 6/6 gives

`5\cdot(6)/(6)+(1)/(6)`
`(30)/(6)+(1)/(6)`
