Verified Answer :

A) 2m+4=5 , is the result of cross multiplying



Answer:

2m + 4 = 5

if \(\frac{m+2}{5}=\frac{1}{2}\) then option (a) is true

Step-by-step explanation:

Given expression \(\frac{m+2}{5}=\frac{1}{2}\)

We have to choose from the given option one that is true about the given expression.

Consider the given expression \(\frac{m+2}{5}=\frac{1}{2}\)

Cross multiply the terms, we get,

2 (m+2) = 5 × 1

Simplify by multiplying, 2 with each term in bracket , we have,

2m + 4 = 5

Thus, we get correct option as option (a)

Thus, if \(\frac{m+2}{5}=\frac{1}{2}\) then option (a) is true
