Question

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

Answer 1

Answer:

m = 2.8

Step-by-step 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

Answer 2

Answer:

2.8

Step-by-step explanation:

Given that

$\dfrac{2}{5}=\dfrac{m}{7}$

Multiply both sides by 7 to isolate m

$\dfrac{2}{5}\times7=\dfrac{m}{7}\times7$

You'll be left with:

$\dfrac{2}{5}\times7=m$

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

$\dfrac{2}{5}\times7=m$

$\dfrac{2\times7}{5}=m$

$\dfrac{14}{5}=m$

2.8 = m
