Question

Write each of the following as decimals:

(i) $\frac{22}{10}$
(ii) $\frac{3}{2}$
(iii) $\frac{2}{5}$

Answer 1

(i) $\frac{22}{10}$
Since the denominator is ten, the decimal is 2.2.

(ii) 3/2
Making the denominator 10, we have
3/2

= $\frac{3\times 5}{2\times 5}$
= $\frac{15}{10}$
= 1.5

(iii) 2/5
Making the denominator 10, we have
2/5
= $\frac{2\times 2}{5\times 2}$
= $\frac{4}{10}$
= 0.4
