Question

A high rise apartment building in New York has 15 floors with 26 apartments on each floor. There are 3 kinds of apartments in the building: one-, two-, and three-bedroom. If each floor has the same number of these kinds of apartments, how many of each kind are in the building?

Answer 1

Angela, I hope you are still up!

 

If there are 15 floors and 26 apartments on each floor, then there are 15 x 26 apartments = 390 apartments.

 

If there are 3 kinds of apartments and an equal number of each, then that's the definition of division, right?  390 / 3 = 130 of each apartment.
