DAV Class 5 Maths Chapter 4 Worksheet 7 Notes

Example 1.
Find $$\frac{3}{4}$$ of $$\frac{1}{2}$$.
Solution:

Consider a rectangle. Make it half. Divide each part into four equal parts.
We want to find out $$\frac{3}{4}$$ of $$\frac{1}{2}$$. So we shade three parts of four parts of the half.

The shaded portion is $$\frac{3}{8}$$ of the whole.
Hence, $$\frac{3}{4}$$ of $$\frac{1}{2}$$ is $$\frac{3}{8}$$.

Example 2.
Let us multiply $$\frac{1}{5}$$ of $$\frac{2}{7}$$.
Solution:
$$\frac{1}{5} \times \frac{2}{7}=\frac{1 \times 2}{5 \times 7}$$ = $$\frac{2}{35}$$
(Multiply the numerator separately 35 Multiply the denominator separately)

Example 3.
Multiply $$2 \frac{2}{5}$$ and $$8 \frac{1}{2}$$
Solution:

Example 4.
Multiply $$\frac{1}{5}$$, $$\frac{5}{7}$$ and $$\frac{2}{3}$$.
Solution:

Remember: In order to multiply two fractional numbers, we multiply the numerators and the denominators separately.
