# Simplifying 1/(1-[1/q])... watch

1. This is the last time I leave my work til the night before it is due in.

Does 1/(1-[1/q]) simplify to 1/q - 1? It would really help me if it did but for some reason I don't really know what to do with it! If it doesn't I have gone wrong somewhere else in the question

Thanks.

No it doesn't. Do it like this

(they're equal because I've multiplied the numerator and denominator both by q, so the fraction overall remains unchanged)

Now expand out and simplify.
3. Thanks for the response. I've worked out what I did wrong. I was meant to be working with powers, and treated them just as numbers.
