If 45 cookies will serve 15 students how many cookies are needed for 30 students?

Ratio and rate problems
Asked Dec 07, 2012

If you are looking for a place to share your travel photos and stories, then try BigRoom.

for every 15 students you need 45 cookies. There are 2 groups of 15 students in 30. (15x2=30) so that means you need 2 groups of 45 cookies because you have 2 groups of 15 students.

SO the answer is 45x2=90

Hope that helps :)
