Question

Write the following number as decimal:

$40+\frac{6}{10}+\frac{9}{100}+\frac{5}{1000}$

Answer 1

Writing the given expansion in decimal

Assigning place value to each digits in the expression $40+\frac{6}{10}+\frac{9}{100}+\frac{5}{1000}$

The given number can be written in the form of

$\begin{array}{rcl}40+\frac{6}{10}+\frac{9}{100}+\frac{5}{1000}& =& 4\times 10+0\times 1+6\times \frac{1}{10}+9\times \frac{1}{100}+5\times \frac{1}{1000}\\ & =& 40+0+0.6+0.09+0.005\\ & =& 40.695\end{array}$

Thus, the given number in decimal will be $40.695$.
