    Answer: 4 gallons
    Step-by-step explanation: A ratio of 2:1 can mean
    2 gallons of blue : 1 gallon of green which equals
    4 gallons of blue : 2 gallons of green since this is just the first ratio multiplied by 2.
    4 gallons + 2 gallons = 6 gallons, so Angelina will need 4 gallons of blue paint.

    Answer:
    4 gallons
    Step-by-step explanation:
    6 gallons of paint means she needs 2 gallons of blue paint per 1 gallon of green paint.
    To make the proper mixture, you need 3 gallons with 2 blue and 1 green. This means you do 6/3=2. You can make 2 total mixtures.
    Multiply 2 blue by the 2 mixtures we need to make. You get 4 gallons of blue paint.
    Multiply 1 green by the 2 mixtures we need to make. You get 2 gallons of green paint.
    Check your work:
    4+2=6
    4/2=2:1
