Question

If x/3 = y/9 then, 3/9 =

Answer 1

Answer:
`(3)/(9) = (x)/(y)`, x = 3 and y = 9

Explanation:

First, we are given the following.

`\displaystyle (x)/(3) =(y)/(9)`

Next, we are being asked to find the following.

`\displaystyle (3)/(9) =\;?`

We can see that we are given a proportion and an incomplete proportion. This means that if
`(x)/(3) =(y)/(9)`, then
`(3)/(9) = (x)/(y)`. Both x and y are in the numerator and 3 and 9 are in the denominator of what is given. If we "rotate" their positions around, we can complete the given proportion to solve.

We can also check our work. If x = 3 and y = 9, then 3/3 and 9/9 will both equal one and 3/9 will be equal to x/y.
