If a mixture of acid and water is supposed to be 6 to 1?

and you only need 4 gallons total solution. How many gallons acid and how many gallons water are needed?

Update:

What if you only need 3 gallons total solution: Then how many gallons acid and gallons water are needed?

    Question 1)

    6 : 1 = 6

    6 +1 = 7

    4*6/7 = 24/7 = 3.43 gal of acid

    4*1/7 = 0.57...........gal of water

    -------------------------------------------------

    Total..............4......gal of solution

    Check: 3.43 : 0.57 = 6 Ok!

    --------------------------------------------------------------------------------------------------------------

    Question 2)

    3 : 4 = 0.75

    From previous answer:

    0.75*3.43 = 2.57 gal of acid

    0.75*0.57 = 0.43 gal of acid

    ------------------------------------------------

    Total……=...3.00.gal of solution

    Check: 2.57: 0.43 = 6 approx Ok!

    ------------------------------------------------------------------------------------------------

    Question 3)

    3 : 4 = 0.75

    0.75/3 = 0.25

    From previous answer:

    0.25*2.57 = 0.64..........gal of acid

    0.25*0.43 = 0.11..........gal of acid

    ------------------------------------------------------

    Total…....= 0.75 = 3/4 gal of solution

    Check: 0.64: 0.11 = 6 approx Ok!

    If the ratio of acid to water is 6:1, then you have 7 total parts of solution. 1/7 of the solution is water, the rest acid.

    4 gallons x 1/7 = 0.57 gallons water, the rest acid (3.43 gallons)

    3 gallons x 1/7 = 0.43 gallons water, the rest acid (2.57 gallons)

    3/4 gallons x 1/7 = 0.11 gallons water, the rest acid (0.64 gallons)
