Question

How do you solve the proportion `5/9=x/63`?

Answer 1

we are given:
`5/9` `=` `x/63`

Here, `x` is the unknown

Leaving `x` at the R.H.S
We shift 63 to the L.H.S (numerator)

so now we get:
`5/9` x 63 `=` `x`
on solving:

`x` `=` 35

So our proportion is :
`5/9` `=` `35/63`
note: on solving the fractions we get the equal value of 0.55 on both the sides
L.H.S = R.H.S hence they are in proportion.
