Hello,
This is my first time posting so I am not entirely sure that this is the right place for this sort of question.
I would like someones opinion on the best way to figure out complicated percentages.
Right now I know of two techniques (maybe three) that I use, but they take to long. For example:
What percentage is 72 of 630? The techniques I would use would be:
1) Find 10%, 5%, 1% of 630 and mix and match to find what is the percentage;
2) Do the long division. (I personally do not like this method because finding multiples of 630 to the remainders is usually a pain); and
3) Fraction them, find a common divisor and do the long division or percentage. (In the past this has proven to be both useful and sometimes a waste of time).
Anyone got any opinions on the matter?
Thank you!
