  1. There cannot be 3 white for every 2 green in 18 blocks. For every 5 blocks, 3 will be white and 2 will be green. 18 is not a multiple of 5.

    If Jeremy drinks 2 pints in 3 days, 60 days is 20 times 3 days. Therefore 2 * 20 = ?

  2. 1st one:

    18 green for x whites
    2 green for 3 white

    so 3/2 = w/18 OR 2/3 = 18/w which is A

    2nd:
    3 days ---> 2 pints
    60 days ---> x pints
    x/2 = 60/3
    x = 2(60/3) = 40 , which is D

    3rd:
    4 bags in 40 minutes
    x bags in 2 hours or 120 minutes
    x/4 = 120/40
    x = 4(120/40) = 12 bags , you are correct

  3. The " 3 white blocks for every 2 green blocks " is just a ratio
    3 : 2 or
    = 6:4 or
    = ... or
    = 27 white : 18 green
