no problem with your explanation... but I will say that it is an adding fractions analog to the subtraction example in this thread.

Just an example.

Fractions are quite useful things in math. And fractions are where a lot of folks lose interest in math. But fractions are really easy if you just remember a few simple rules.

1) to add or subtract, find the common denominator cross multiply
2) to multiply, top times top and bottom times bottom
3) to divide, invert (swap out top/bottom of one fraction) then multiple
4) remember a whole number is really a fraction, the number divided by 1 ergo 1/2/3 is really 1/2 divided by 3/1

If I wanted to express 1 divided by 2/3 then I would write 1/(2/3)
