Let us assume this poorly worded question is a math problem, let us further assume that the numbers are the width of the boards in a mixed width flooring installation.
3"+4"+5"=12"
so each 1" of board is 1/12th of the total.
1 divided by 12= .0833 or 8 1/3 % of the total
so if you multiply 3X 8 1/3 you get 25% (and 3/12ths is 25% so this looks promising)
3"X 8 1/3%=25%
4"X 8 1/3%= 33.333%
5"X 8 1/3%= 41.667
add those up & we get 100% so the work is good & the proof is valid
