$\frac{9}{20} = 9 \div 20 = 0.45$ $9/20 = 9 -: 20 = 0.45$

Explanation:

Another way to look at this is:

$\frac{9}{20} = \frac{9}{20} \times \frac{5}{5} = \frac{9 \times 5}{20 \times 5} = \frac{45}{100} = 0.45$ $9/20 = 9/20 xx 5/5 = (9 xx 5)/(20 xx 5) = 45/100 = 0.45$

0.45

Explanation:

$9 \div 20$ $9-:20$

$\Rightarrow \frac{9}{20}$ $=> 9/20$

Convert the denominator into powers of 2 and 5.

$\Rightarrow \frac{9}{2 \times 2 \times 5}$ $=> 9/(2xx2xx5$

$\Rightarrow \frac{9}{2^{2} \times 5^{1}}$ $=> 9/(2^2xx5^1$

Now multiply both numerator and denominator with 5 to make the powers of 2 and 5 equal.

$\Rightarrow \frac{9 \times 5}{2^{2} \times 5 \times 5}$ $=> (9xx5)/(2^2xx5xx5$

$\Rightarrow \frac{45}{2^{2} \times 5^{2}}$ $=> 45/(2^2xx5^2$

You can combine the bases with same powers

$\Rightarrow \frac{45}{10^{2}}$ $=> 45/10^2$

$\Rightarrow \frac{45}{100}$ $=> 45/100$

$\Rightarrow 0.45$ $=> 0.45$
