DAV Class 5 Maths Chapter 4 Worksheet 11 Notes

I. Division of a fractional number by a whole number.

Example 1.
Divide $$\frac{3}{8}$$ by 2.
Solution:
Look at the figure.

This represents $$\frac{3}{8}$$
Let us divide $$\frac{3}{8}$$ into 2 equal halves.

This represents $$\frac{3}{16}$$
∴ $$\frac{3}{8}$$ ÷ 2 = $$\frac{3}{16}$$
In another manner
$$\frac{3}{8} \div 2=\frac{3}{8} \times \frac{1}{2}=\frac{3}{16}$$
So, dividing $$\frac{3}{8}$$ by 2 actually means multiplying $$\frac{3}{8}$$ with the reciprocal of 2 i.e., $$\frac{1}{2}$$.

Important Note: To divide first change the division sign to the multiplication sign and multiply by the reciprocal of the divisor.

Example 2.
Divide 3$$\frac{1}{7}$$ by 3.
Solution:

II. Division of a whole number by a fractional number.

Example 3.
Divide 5 by $$\frac{2}{3}$$.
Solution:

III. Division of a fractional number by another fractional number.

Example 4.
Divide $$\frac{4}{3}$$ by $$\frac{7}{5}$$.
Solution:
$$\frac{4}{3} \div \frac{7}{5}$$
Here, dividend = $$\frac{4}{3}$$, divisor = $$\frac{7}{5}$$
= $$\frac{4}{3} \times \frac{5}{7}$$ (Multiplying by the reciprocal of divisor $$\frac{7}{5}$$)
= $$\frac{20}{21}$$
