Question

2/5 = x/7
Please answer in decimal form.
X=?

Answer 1

x = 2.8

Explanation:

Hey!!!

We've pretty much simplified the equation, and we're on the last step!

To find what x is, we need to divide 2/5 by 7.

I've put it in some LaTeX:

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

2 ÷
`(5)/(7)` = x (The viniculum in a fraction represents division.)

2 ×
`(7)/(5)` (Division is the same as multiplication by the reciprocal.)

`(14)/(5)` = x

`(14)/(5)` = 2
`(4)/(5)` = 2.8

Thus, the answer is
`\boxed{x = 2.8}`.

Check:

2.8 ÷ 7 = 0.4 = 2/5

So, we are correct!

Answer 2

x=2.8

Explanation:

Cross multiply to solve

2/5 = x/7

5x=14

Divide by 5 on both sides

x=2.8

Hope this helps! :)
