Cortez Mccormick · Answer 1

so first you have to make a common denominator of 30 to see how many people in the class.

3/10 • 3 = 9/30

3/5 • 6 = 18/30

then you have to add them together.

18 + 9 = 27

then you subtract 30 from 27.

30 - 27 = 3

so 3 students are wearing shirts other than blue or white
