Question

Express the following in p/q form i)1.53 I)0.421

Answer 1

$i ) Given \: rational \: number = 1.53$

$\red{ \frac{p}{q} \:form \: 1.53 } \\= 1.53 \times \frac{100}{100}\\= \frac{1.53 \times 100}{100}\\\green {= \frac{153}{100}}$

$ii) Given \: rational \: number = 0.421$

$\red{ \frac{p}{q} \:form \: 0.421} \\= 0.421 \times \frac{1000}{1000}\\= \frac{0.421 \times 1000}{1000}\\\green {= \frac{421}{1000}}$
