1/5 of a gallon of milk poured into 2 separate cups

You're essentially dividing 1/5 by 2.

1     2
-- /  -- 
5     1

Change this into

1      1        1
--  *   -- =    --
5       2      10

So the question says basically to do 1/5 divided by 2 (or 2/1) instead of that, do 1/5 multiplied ( opposite of divide ) by 1/2 (opposite of 2/1) and that's 1/10. Please make me brainliest ❤

You can find the area of a rectangle by multiplying the length and height. so multiply 1/2*7/4(which is the simpler version of 1 3/4) and you get 7/8 as your answer.
