Explain the process of cancellation of numbers.

Process of cancellation of numbers :

In cancellation method we just cancel the common factors from numerator and denominator and we divide numbers from numerator and denominator with common factors.

For example,

$\frac{5}{9} \times \frac{18}{5} $

Here, 5 is common factor, so we can cancel them.

$= \frac{1}{9} \times \frac{18}{1}$

$ = \frac{18}{9}$ 

We can write 18 as $9 \times 2$

$= \frac{9 \times 2}{9}$

Here, 9 is common factor, so we can cancel them.

$= \frac{2}{1} = 2$.
