Dividing Decimals
When dividing decimals, it may be possible to change the calculation so that it involves dividing whole numbers.To evaluate
\[\frac{20.4}{0.05}\]
multiply numerator and denominator by 100 to obtain \[\frac{20.4}{0.05} \times \frac{100}{100}= \frac{2040}{5}\]
.Now carry own the calculation using normal long division, obtaining the result 408.
