Question

Write the following in the expanded notation

$49.137$

Answer 1

Multiply L.H S by $10s$and Divide R.H.S by$10s$

$49.137$

$$\begin{gathered} =4\times 10+9\times 1+0.1+0.03+0.007 \\ =40+9+\frac{1}{10}+\frac{3}{100}+\frac{7}{1000} \end{gathered}$$

Hence, the expanded notation of $49.137$ is $40+9+\frac{1}{10}+\frac{3}{100}+\frac{7}{1000}$
