Question

In art class students are mixing blue and red paint to make purple paint. Madelyn mixes 3 cups of blue paint and 10 cups of red paint. Arturo mixes 1 cup of blue paint and 4 cups of red paint. Whose purple paint will be redder?

Answer 1

To compare the purple paints that Madelyn and Arturo made, you need to find the ratio of red to blue in each mixture. You can do this by dividing the amount of red paint by the amount of blue paint.

For Madelyn, the ratio of red to blue is:

10 / 3 = 3.33

For Arturo, the ratio of red to blue is:

4 / 1 = 4

Since Arturo has a higher ratio of red to blue, his purple paint will be redder than Madelyn’s.
