Add:
$\frac{1}{10} +\frac{1}{20} +\frac{1}{40} +\frac{1}{100}$.
Given:
$\frac{1}{10} +\frac{1}{20} +\frac{1}{40} +\frac{1}{100}$.
To do:
We have to find the given sum.
Solution:
To find the given sum, we have to first find the LCM of the denominators.
LCM of 10, 20, 40, 100 is 200.
Therefore,
$\frac{1}{10} +\frac{1}{20} +\frac{1}{40} +\frac{1}{100}=\frac{1\times20+1\times10+1\times5+1\times2}{200}$
$=\frac{20+10+5+2}{200}$
$=\frac{37}{200}$
Hence, $\frac{1}{10} +\frac{1}{20} +\frac{1}{40} +\frac{1}{100}=\frac{37}{200}$.
