In a classroom 3/8 of the students are wearing blue shirts and 1/4 are wearing white shirts.There are 24 students in the classroom. How many kids are wearing a shirt other then blue or white?

Answer 1

b = 3s/8, w= s/4, s=24

kids wearing other than w or b = (1- (3/8) - (1/4)) x 24 = (3/8)x24 = 9 students

3/8 x 24 = 9 wearing blue

1/4 x 24 = 6 wearing white

9+9+6 = 24
