Question

How can -1 divided by -2.5 equal 0.4?

Answer 1

`2/5=4/10=0.4`

Explanation:

We know that a negative divided by another negative will equal a positive, so we can ignore the negative signs.

Let's use `5/2` instead of `2.5`

`1/1 divide 5/2=2/5`

To convert to a fraction, we can set the denominator equal to `10`.
`2/5=4/10=0.4`
