Kelly's company is painting a building a unique shade of purple. She needs 12 pints of red paint for every 8 pints of blue paint. Using that ratio, if she uses 65 pints of paint how much blue paint is needed?
1 Answer
Explanation:
Multiply the fraction of pints of blue by the total number of pints.
#65 * (2/5) = 26#
For red paint, you would do
#65 * (3/5) = 39#
To check if we are correct,
#26 + 39 = 65#
#26:39 -> 26/13 : 39/13 -> 2:3#
