Ms. groves has trays of paint for students in her art class. each tray has 5 colors. one of the colors is purple. what fraction of the colors in 20 trays is purple?

Fraction of purple color is 1/5

Step-by-step explanation:

Number of color in 1 tray = 5

Number of colors in 20 trays = 20x5 = 100

Since  each tray has purple color

so number of purple color = 20

Fraction for purple color =  number of purple color/total  number of colors

i may be incorrect but i believe that her first error was in step one when she multiplyed her equation by 1/4 when she should have divided it by 1/4
