Question

[x+2/3x] / [x+2/3x] for x=7

Answer 1

What do we do when we divide fractions by other fractions? Do you remember?

Answer 2

they are not fractions its x+2 divided by 3x

Answer 3

That's a fraction. When you divide one fraction by another you have to take the reciprocal, so you will have:
(x+2)/3 * 3x/(x+2). You could just plug in 7 for x in this case, but for some problems that you have in the future, you will have to take the reciprocal.

Answer 4

ok, but these are not fractions. It is [x+2 divided by 3x] divided by [x+2 divided by 3x]

Answer 5

A fraction is when something is divided by another.
