# How do you simplify (1/4)(-9)(1/5)?

Apr 16, 2017

$- \frac{9}{20}$

#### Explanation:

We can consider this to be the multiplication of 3 fractions.

$\text{That is }$

$\frac{1}{4} \times \frac{- 9}{1} \times \frac{1}{5}$

$\text{there is no "color(blue)"cancelling" " between numerator/denominator}$

$\text{Hence multiply remaining values on numerator/denominator}$

$\Rightarrow \frac{1 \times - 9 \times 1}{4 \times 1 \times 5}$

$= \frac{- 9}{20}$

$= - \frac{9}{20} \leftarrow \textcolor{red}{\text{ in simplest form}}$
