Ok He makes six quarts of brown paint by mixing equal qualities of yellow paint and violet paint The violet paint is made from one third red paint and two thirds of blue paint.

How much red paint does he use?

How much blue paint does he use?

what ia the percentage of the brown paint is made of the blue paint?

Hmm, great question. If you use equal quantities of yellow and violet, that would mean 6 quarts divided by 2. In this tree we know that there is 3 quarts of yellow paint, while the violet paint is made of blue and red. 1/3 of violet 3 quarts is one US quart, so 1 quart of red paint was used. Then 2/3 of 3 quarts is 2 US quarts, so 2 quarts of blue paint.And because six quarts of brown paint was partially made from 2 quarts of blue paint 2/6=0.33333333333333333(so on) multiplied by 100 to fufill the percentage, 33.333333(so on)%.

So for question number 1, one quart of red paint. Number 2, two quarts of blue paint. Num 3, 33.333333%.

And the 6 quarts of brown paint was made by three quarts of yellow paint, one quart of red paint, and two quarts of blue paint.

Thx 4 the great question
