Answer:
540
Step-by-step explanation:
Okay so 1/4 of the dance is boys. That means that 45 boys = 1/4 of the dance. Take 45 and multiply it by 4. This number is 180 and and that is the total number of people at the dance. If 1/3 of the students went to the dance, then 1/3 of the school = 180. Multiply 180 by 3 to get 540.
45(4) = 180 = 1/3 of school
180(3) = 540 = total numbers in school.
Hope this helps!
