Question

use structure draw a picture to show how to find $4 \times \frac{3}{5}$.

Explanation:

Step1: Define unit fractions

We represent $\frac{3}{5}$ as 3 parts out of 5 equal sections in a whole (rectangle).

Step2: Repeat for 4 wholes

Draw 4 identical rectangles, each divided into 5 equal parts, and shade 3 parts in each rectangle.

Step3: Count total shaded parts

Total shaded sections = $4 \times 3 = 12$, each section is $\frac{1}{5}$. So total is $\frac{12}{5}$ or $2\frac{2}{5}$.

Answer:

1. Draw 4 identical rectangles.
2. Divide each rectangle into 5 equal smaller rectangles.
3. Shade 3 out of the 5 smaller rectangles in each of the 4 large rectangles.
4. Count all shaded smaller rectangles: there are 12, so $4 \times \frac{3}{5} = \frac{12}{5} = 2\frac{2}{5}$.
