# Karl wants to fertilize his 6 acres. If it takes 8 2/3 bags of fertilizer for each acre, how much fertilizer does Karl need to buy?

$52$ bags

#### Explanation:

There are 6 acres. He needs $8 \frac{2}{3}$ for each acre.

WE could say: $8 \frac{2}{3} + 8 \frac{2}{3} + 8 \frac{2}{3} + 8 \frac{2}{3} + 8 \frac{2}{3} + 8 \frac{2}{3}$

and then just ad them all together.

However, multiplication is the short cut for repeated addition.

So it is quicker and easier to do

$6 \times 8 \frac{2}{3}$

=${\cancel{6}}^{2} \times \frac{26}{\cancel{3}}$

=$52$ bags
