– 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.
