Answer
$\frac{13}{50}$
Work Step by Step
$\frac{1}{50}$ + $\frac{1}{5}$ + $\frac{1}{25}$
The LCD (least common denominator) is 50, so multiply $\frac{1}{5}$ by $\frac{10}{10}$ and $\frac{1}{25}$ by $\frac{2}{2}$ so their denominators equal 50.
$\frac{1}{5}$ $\times$ $\frac{10}{10}$ = $\frac{10}{50}$
$\frac{1}{25}$ $\times$ $\frac{2}{2}$ = $\frac{2}{50}$
Now, add all three fractions together:
$\frac{1}{50}$ + $\frac{10}{50}$ + $\frac{2}{50}$ = $\frac{13}{50}$
