Question

McGruff Building Co. is in charge of building a new hotel. The owner of the hotel tells the company that the ratio of one person rooms to two person rooms in the hotel should be 2:3.

If the building company has bulit 36 two person rooms, how many one person rooms must they build to have the correct ratio of rooms?

Answer 1

The given ratio of one person rooms to two person rooms in the hotel is 2 : 3

Let one person room be x .

if the building company had built 36 two person rooms in the hotel then,

2 : 3 = x : 36

so,

solving it we get x = 24

Hence 24 one person rooms must be build to have the correct ratio of rooms.
