Explanation:
it says here this is a college question ? wow ..
anyway, remember what % calculation means.
it splits a main amount into 100 equal parts (1% is 1/100 of 100%).
so, if we want to know how many % another number is of the original 100%, we need to see how often 1% (original 100% divided by 100) fits into that number.
so, for any % question always identify 100% and 1%.
100% = 60,800,000
1% = 100%/100 = 60,800,000/100 = 608,000
how many % are 8,900,000 ?
8,900,000 / 608,000 = 14.63815789...%
