Black_prince [1.1K]

Answer:

You will use 2 cups of blue paint for 4 cups of yellow paint.

Step-by-step explanation:

Given that:

There is 1/3 cup of blue paint for every 2/3 cup of yellow paint

We will find unit rate in terms of yellow paint.

2/3 cups of yellow paint = 1/3 cup of blue paint

Multiplying both sides by 3/2

\frac{2}{3}*\frac{3}{2}=\frac{1}{3}*\frac{3}{2}\\1\ cup\ of\ yellow\ paint = \frac{1}{2}\ cup\ of\ blue\ paint

Now,

4 cups of yellow paint = 4*\frac{1}{2} cups of blue paint

4 cups of yellow paint = 2 cups of blue paint

Hence,

You will use 2 cups of blue paint for 4 cups of yellow paint.
