`1/2 = ( 1 xx 5 ) / ( 2 xx 5 ) = 5/10`
\(\dfrac{1}{3}=\dfrac{1\times25}{1\times50}=\dfrac{25}{100}\)
\(\dfrac{1}{4}=\dfrac{1\times20}{5\times20}=\dfrac{20}{100}\)
`1/5=(1×2)/(5×2)=2/10`
`1/8=(1×125)/(8×125)=125/1000`
\(\dfrac{1}{4}=\dfrac{1.25}{4.25}=\dfrac{25}{100}\)
\(\dfrac{1}{5}=\dfrac{1.2}{5.2}=\dfrac{2}{10}\)
\(\dfrac{1}{8}=\dfrac{1.125}{8.125}=\dfrac{125}{1000}\)
