Question

. -6.6 is some number of times as large as 5. What is the number?

Answer 1

Given that -6.6 is some number of times as large as 5.

Let x be the required number.

Given can be written as follows.

$-6.6=5\times x$$\text{Use 6.6=}\frac{66}{10}\text{.}$

$-\frac{66}{10}=5x$

Dividing by 5 into both sides, we get

$-\frac{66}{10\times5}=\frac{5x}{5}$

$-\frac{66}{50}=x$

Dividing 66 by 50, we get 1.32.

$x=-1.32$

Hence the required number is -1.32.
