Question

Convert the following fractions into decimal numbers.

(i) 3$\frac{3}{5}$ (ii) 3$\frac{19}{25}$

Answer 1

(i) 3 $\frac{3}{5}$
Keep the whole number 3 as such, we can find a fraction equivalent to $\frac{3}{5}$ with denominator having a power of 10.

3 + $\frac{3}{5}$ = 3 + $\frac{3\times 2}{5\times 2}$ = 3 + $\frac{6}{10}$ = 3.6

$\left[1.5\right]$

(ii) 3$\frac{19}{25}$ = 3 + $\frac{19}{25}$= 3 + $\frac{19\times 4}{25\times 4}$ = 3+$\frac{76}{100}$=3.76

$\left[1.5\right]$
