I will do one of them in a systematic way, you then should be able to reason out the others without any actual work
MIX D
conentrate:water = 3:5
let the amount of concentrate be 3x
and the amount of water be 5x
(notice 3x:5x = 3:5)
then 3x + 5x = 1
8x = 1
x = 1/8
so concentrate = 3x = 3/8 of a cup
water = 5x = 5/8 of a cup
notice how 3/8 + 5/8 = 1
notice 3/8 : 5/8 = 3:5
can you now do the others by observing how the 8 was obtained?
