Example: How do you work out 12 / 6 × 3 / 2 ?

Multiplication and Division rank equally, so just go left to right:

First 12 / 6 = 2, then 2 × 3 = 6, then 6 / 2 = 3

It won't work like that this time around though because there is a bracket, which implies the 2 and (9+3) should both belong to the denominator. Therefore you can't move the bracket up to the numerator.

well the example   12 / 6 × 3 / 2  is quite easy to solve by using the division represented as fractures law because i do this:

12                   3

___    x      ___ = 3

6        2
