– 0.7
Step-by-step explanation:
Given expression is [tex]\frac{1}{2}(-1.4 m+0.4)[/tex]
To simplify this expression [tex]\frac{1}{2}(-1.4 m+0.4)[/tex] we get equivalent expression.
Multiply and Divide the expression by two.
[tex]\Rightarrow\left(\frac{-1.4}{2} m+\frac{0.4}{2}\right)[/tex]
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, [tex]\frac{1}{2}(-1.4 m+0.4)[/tex] = –0.7 m + 0.2.
