Question

What value of x makes this proportion true? 25/20 = x/4

Answer 1

x = 5

hope this helps :))

Answer 2

The value of x is 5.

Explanation:

The given proportion is
`(25)/(20)=(x)/(4)`

In order to find the value of x for which the proportion is true, we can multiply both sides by 4.

`(25)/(20)\cdot4=(x)/(4)\cdot4`

On simplifying, we get

`(25)/(5)=x\\\\x=5`

Thus, the value of x is 5.

Let us check if the proportion is true for x=5 or not.

Substitute x = 5 in the given equation.

`(25)/(20)=(5)/(4)`

Simplify the left hand side

`(5*5)/(5*4)=(5)/(4)\\\\(5)/(4)=(5)/(4)`

We got a true result. Hence, the proportion is true for x=5.

Thus, the value of x is 5.
