Q 1 - Multiply the fractions using an area model$\frac{1}{5}$ ×$\frac{1}{3}$

Answer : A

Explanation

Step 1:

In this problem, we want to find $\frac{1}{5}$ of $\frac{1}{3}$

Step 2:

First we divide the height of a rectangle into 3 equal parts. We shade one part to represent $\frac{1}{3}$

Step 3:

Next we divide the width into 5 equal parts and shade 1 part to make it $\frac{1}{5}$.

Step 4:

Now we can figure out the product. The part where the shading overlaps represents the numerator. The total number of parts represents the denominator. There are 15 parts in total and 1 of the parts overlaps.

Step 5:

So, the product is $\frac{1}{5}$ ×$\frac{1}{3}$ = $\frac{1}{15}$

Step 2:

First we divide the height of a rectangle into 2 equal parts. We shade one part to represent $\frac{1}{2}$.

Step 3:

Next we divide the width into 5 equal parts and shade 2 parts to make it $\frac{2}{5}$.

Step 4:

Now we can figure out the product. The part where the shading overlaps represents the numerator. The total number of parts represents the denominator. There are 10 parts in total and two of the parts overlap.

Step 5:

So, the product is $\frac{2}{5}$ × $\frac{1}{2}$ = $\frac{2}{10}$
