What number makes the expressions equivalent? enter your answer in the box.

1/2 (–1.4m + 0.4) = m + 0.2

– 0.7

Step-by-step explanation:

Given expression is  

To simplify this expression  we get equivalent expression.

Multiply and Divide the expression by two.

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,  = –0.7 m + 0.2.
