Do anything in BRACKETS first,
then ORDERS (i.e. POWERS)
then DIVISONS and MULTIPLICATIONS
then ADDITIONS and SUBTRACTIONS.
So you have to do the division first...
and then the addition and subtraction left to right...
3. You need to find the lowest common denominator.
The lowest common denominator is 12, since it is the smallest number that 2, 3 and 4 all go into.
You need to use BODMAS, so do everything in brackets first.
To divide fractions you use "stay, change, flip". In other words, keep the first fraction the same, change the divide to a times, and flip the second.
Then to multiply fractions, look for anything that cancels, then times tops and times bottoms.
