Question

Megan collected $\small \frac{1}{3}$ of a bag of leaves. Sally collected times as many bags as Megan. How many bags did Sally collect?

Answer

When we multiply a fraction by a whole number, we first want to make the whole number into a fraction. We do that by putting the whole number over Then we multiply like normal.

$\small \small \frac{3}{1}\times\frac{1}{3}=\frac{3}{3}$

$\small \frac{3}{3}=1$ Because can go into $\small 3$ an even $\small 1$ time.

Sally collected $\small 1$ bag of leaves.
