Question

There were 700 people in the auditorium. 60% of them were adults and the rest were children. how many adults were in the auditorium? how many children?

Answer 1

$.60 \times 700 = 420 \\ 700 - 420 = 280$
First I found the number of adults by multiplying .60 by 700. It was 420. From there all I had to do was subtract it from 700. Revealing the number of children to be 280.
