Question

Number of dinners = 125
Individual portion = 8 oz.
Size of can = 32 oz.

Number of cans required = _____.

Answer 1

if the size of one can is 32 oz and all you need per serving is 8 oz, you would take 32 and divide it by 8 so you know how many servings per can.

Answer 2

after that you can take 125 and divide that by your answer. (32/8=4) so you could do 125/4 and you get 31.25 so you should need 31.25 cans (i may be wrong i tend to over think things)
