My sister needs with her homework and i'm too stressed to her.

A:

There are 48 rooms in the hotel. This is because if each room has 4 beds, you would want to divide 192 by 4 to get 48.

B:

There are 144 windows in the hotel. If there are 3 windows per room, you would multiply the amount of rooms by 3, or the amount of windows.

A.

There's 48 rooms. This is because 192 beds in total divided by 4 beds per room equals 48 rooms.

B.

There are 144 windows. This is because 48 rooms multiplied by 3 windows equals 144 windows in total.

I hope this helped!
