Question

In a classroom, 1 10 of the students are wearing blue shirts , and 2 5 are wearing white shirts. there are 30 students in the classroom. how many students are wearing shirts other than blue shirts or white shirts?

Answer 1

To solve this question, (1,10) and (2,5) need to be changed to the denominator of 30. Multiply the 10 by 3 to get (3,30) and 5 by 6 to get (12,30). Add those together to find the other students not wearing blue or white shirts.
