Question

The ratio x : y is equal to 4x : 3.
Work out the value of y.
y =

Answer 1

y =
`(3)/(4)`

Explanation:

Express the ratios in fractional form

`(x)/(y)` =
`(4x)/(3)` ( cross- multiply )

4xy = 3x ( divide both sides by 4x )

y =
`(3x)/(4x)` =
`(3)/(4)`

Answer 2

y=3/4

Explanation:

4x/3 = x/y

or, 1/y= 4/3

or, y=3/4
