For every 1 cup of blue paint, cups of red paint are needed
For every 1 cup of red paint, cup of blue paint is needed
For every 4 cups of red paint, cups of blue paint are needed
<em><u>Solution:</u></em>
Given that, there are 3 1/3 red cups of paint for every 1 1/3 cups of blue paint
Therefore, ratio is
Let "x" be the cups of red paint needed
Then we get,
This forms a proportion
Therefore, 10/4 cups of red are needed for 1 cup of blue
<h3><u>For every 1 cup of red paint, ___ cup of blue paint is needed</u></h3>Let "x" be the cups of blue paint needed
Then, we get
This forms a proportion
Thus, 4/10 cups of blue are needed for 1 cup of red paint
<h3><u>For every 4 cups of red paint,___ cups of blue paint are needed</u></h3>Let "x" be the cups of blue paint needed
Then, we get
This forms a proportion
Thus 16/10 cups of blue paint are needed for every 4 cups of red paint
