Answer 8

Ratio of CUPS OF BLUE PAINT to CUPS OF RED PAINT. is 3:1.

So how many cups of blue paint did she pour in, and how many cups of red paint?

Answer 9

i am guessing 3 cups of red and 1 cup of blue?

Answer 10

No, you got it backwards.. since it's blue paint to red paint, and the ratio is 3:1, it would be 3 cups of blue and 1 cup of red.

So you can write the sentence:

Lara poured 3 cups of blue paint mixed with 1 cup of red paint.

Answer 11

OMG thanks

Answer 12

How many cups of red paint should Lara add to each cup of blue paint to make the shade of purple? Explain your reasoning.

I think they want you to keep the same ratio of 3 cups of blue paint to 1 cup of red paint.

So like if you put 6 cups of blue paint, you would put 2 cups of red paint, etc.

So you have to find the cube root of 3 to see how many cups of red paint you put in 1 cup of blue paint.

Answer 13

is this the answer ?
