Angelina is painting her room. She wants a very specific shade of bright blue paint, so she mixes blue and green paint in a ratio of 2:1 . If she needs 6 gallons of paint, how many gallons of blue paint should she buy? Use a tape diagram to help organize your thinking.(1 point)

Tape diagram:

Blue paint: 2 units
Green paint: 1 unit

If the total ratio is 3 units (2 + 1), and 6 gallons of paint is needed, we can set up a proportion:

3 units --> 6 gallons

1 unit --> 6/3 = 2 gallons

Therefore, Angelina should buy 2 gallons of blue paint.
wrong please give me the right answer
My apologies for the confusion. Let's try to solve it correctly again:

Tape diagram:

Blue paint: 2 units
Green paint: 1 unit

To find out how many gallons of blue paint Angelina should buy, we first need to determine the total number of units in the ratio.

In this case, the total ratio is 2 + 1 = 3 units.

Since Angelina needs 6 gallons of paint, we can set up a proportion:

3 units --> 6 gallons

1 unit --> 6/3 = 2 gallons

Since Angelina wants to buy blue paint, she should buy 2 gallons of blue paint.
