**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.
