# 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?

Multiply the fraction of pints of blue by the total number of pints.

To find out how much blue paint is needed using the given ratio of 12 pints of red paint for every 8 pints of blue paint, we can set up a proportion:

12 pints of red paint / 8 pints of blue paint = 65 pints of total paint / x pints of blue paint

Cross multiplying:

12 * x = 8 * 65

Solving for x:

12x = 520

x = 520 / 12

x ≈ 43.33 pints

So, approximately 43.33 pints of blue paint are needed.
