So in this case when working out this conundrum it is four divided one hundred which is exactly25. After you have completed this you need to multiply the result which is 25 by the top number of the fraction which is three and the result is 75.
This is the case in all sums that you have to work out. If you want to work out a percentage of a number then this is also a relatively easy process to do. All you need to follow are a few simple rules. Take for example the case of expressing if you need to work out 10 per cent of 100 dollars. All you need to do in order to work out what exactly 10 per cent of $100 is you have to multiply 0.1 x 100 which should give you 10. So the result is 10 dollars. This is because it is 10 per cent of $100.
Anything which shows that you need to work out where it says of, in the majority of cases means it is a multiplication question. This is exactly the same case for let's say 20 per cent of $200. All you need to do in this case is to multiply 0.2 x 200 which should give you a result of 40. If a jacket was originally $200 with a 20 per cent reduction it will now cost $160.
