Question

Is 48/9 and 16/3 proportional

Answer 1

Yes. They would be proportional. A comparison in this instance would be proportional if there was some relation between them. Let's look at them :

$\frac{48}{9}$ and $\frac{16}{3}$

Once you divided 48 by 16, you would get 3, which implies that 48 divided by 3 is 16. So in the same time, you would have to do the same to the denominator, which you do to the numerator. 9 divided by 3 is 3.

This makes the relationship proportional.

Answer 2

Yes, because of you divide by 3, 48/9 can be simplified to 16/3.
