Question

$1.01\times 1.01=\_\_$

Answer 1

When we remove a decimal from a given number then the number of zeros is added to the denominator

$$\begin{gathered} 1.01\times 1.01 \\ =\frac{101}{100}\times \frac{101}{100} \\ =\frac{10201}{10000} \\ =1.0201 \end{gathered}$$

Hence, $1.01\times 1.01=1.0201$
