Answer 1

-0.7

Explanation:

Answer 2

– 0.7

Explanation:

Given expression is
`(1)/(2)(-1.4 m+0.4)`

To simplify this expression
`(1)/(2)(-1.4 m+0.4)` we get equivalent expression.

Multiply and Divide the expression by two.

`\Rightarrow\left((-1.4)/(2) m+(0.4)/(2)\right)`

To simplify the expression again, we get,

⇒ (–0.7 m + 0.2)

So, we found the coefficient of m is –0.7.

The missing number is –0.7

Hence, –0.7 makes the expression equivalent.

Therefore,
`(1)/(2)(-1.4 m+0.4)` = –0.7 m + 0.2.
