Answer:
3
B
Step-by-step explanation:
Argument
According to the directions, the ratio of red to blue is 5/6
Red / Blue = 5/6
If there are 10 quarts of Red paint, there will be x quarts of blue paint.
Proportion
5/6 = 10/x
Solution
Cross multiply
5x = 6 * 10
Combine the right
5x = 60
Divide by 5
5x/5 = 60/5
x = 12
So the blue requires 12 quarts of paint.
=============
4 cans provide 12 quarts of blue
1 can provides x quarts of blue
4/1 = 12/x Cross multiply
4x = 12*1 Combine
4x = 12 Divide by 4
4x/4 = 12/4
x = 3
Answer
Each can contains 3 quarts of blue
