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

Answer:

Explanation:

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

$\frac{7.75\text{ dollars}}{5\frac{1}{6}lb}$

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

$5\frac{1}{6}=5+\frac{1}{6}$

multiplying 5 by 6/6 gives

$5\cdot\frac{6}{6}+\frac{1}{6}$$\frac{30}{6}+\frac{1}{6}$
