For example, lets takeĀ \(\frac{25}{100}\)
We need to first factor the numerator and denominator to find the common numbers which we can simplify it by.
\(\frac{25}{100} = \frac{5 \times 5}{5\times 5\times 4}\)
If we divide by 5 x 5 on both the numerator and denominator because both of them have it in common, we will get the simplest form.
\(\frac{5 \times 5\div 5 \div 5}{5\times 5\times 4\div 5\div 5} = \frac{1}{4}\)
