Question

What is answer to this equation 2/5=m/7? what does m =

Answer 1

2.8

Explanation:

Given that

`(2)/(5)=(m)/(7)`

Multiply both sides by 7 to isolate m

`(2)/(5)*7=(m)/(7)*7`

You'll be left with:

`(2)/(5)*7=m`

Then simply do the operations to get the value of m:

`(2)/(5)*7=m`

`(2*7)/(5)=m`

`(14)/(5)=m`

2.8 = m

Answer 2

m = 2.8

Explanation:

Multiply both sides of the equation by the inverse of the coefficient of m. That coefficient is 1/7, so its inverse is 7/1 = 7. Then you have ...

7·2/5 = 7·m/7

14/5 = m . . . . . . . . simplify

m = 2 4/5 = 2.8 . . express the number in a manner that makes sense to you
