# How do you simplify 13\frac{7}{10}\times 7?

May 26, 2018

$\frac{959}{10}$

#### Explanation:

We have
$13 \frac{7}{10} = \frac{137}{10}$
and
$\frac{137}{10} \cdot 7 = \frac{959}{10}$

$13 \frac{7}{10} \cdot 7 = 95 \frac{9}{10}$

#### Explanation:

I think the simplest way here is to take
$13 \frac{7}{10} \cdot 7 = 13 \cdot 7 + \frac{7 \cdot 7}{10}$
$= 91 + \frac{49}{10}$
Remember that $\frac{40}{10} = 4$
This gives
$= 91 + 4 \frac{9}{10}$
$= 95 \frac{9}{10}$
