Question

Find the missing value: -2/5 ___ = 1
i picked -2/5 am I right

Answer 1

The missing value is
`-(5)/(2)`

Explanation:

Let
`x` be the missing value, then
`-(2)/(5)x=1`.

We now multiply both sides of the equation by the reciprocal of
`-(2)/(5)` which is
`-(5)/(2)`.

This will give us,

`-(5)/(2)* - (2)/(5)x= -(5)/(2)* 1`.

We cancel out common factors to obtain,

`x= -(5)/(2)* 1`.

This finally simplifies to,

`x= -(5)/(2)`.
