Question

In art class students are mixing black and white paint to make gray paint. Sophia mixes 3 cups of black paint and 4 cups of white paint. Jeriel mixes 9 cups of black paint and 10 cups of white paint. Use Sophia and jeriels percent of white paint to determine whose gray paint will be lighter

Answer 1

Sophia's paint is lighter.

Explanation:

percent = part/whole × 100%

Sophia:

3 cups black, 4 cups white

total: 7 cups

white percent = 4/7 × 100% = 57%

Jeriel:

9 cups black, 10 cups white

total: 19 cups

white percent = 10/19 × 100% = 53%

Sophia's paint is lighter.
