Question

What is `(1/4 + 11/8)/(2/13+1/26)`?

Answer 1

Nice to know: `(a/b)/(c/d) " simplifies "(a xx d)/(b xx c)`

Explanation:

There is a very nifty short cut when you need to divide layers of fractions such as in this example.

In `(a/b)/(c/d) " this simplifies to "(a xx d)/(b xx c)`

Just be sure that you know where the MAIN division is.

`(a/b)/c rArr (a/b)/(c/1)" while " a/(b/c) rArr (a/1)/(b/c)`

I have found this very useful!
