There will be 15 pints needed.
Let the total pints of red needed be x.
Based on the information given, this can be used in forming an equation as:
2/3 = x/9
Cross multiply
(2 × 9) = (3 × x)
18 = 3x
x = 18/3
x = 6
Therefore, 6 pints of red paint are needed.
Therefore, the total pints needed altogether will be:
= 6 red + 9 yellow
= 15 paints.
In conclusion, 15 pints will be needed.
