Question

a hotel has 128 rooms on each floor there are 4 rooms n all. if 334 rooms are clean, how many rooms still need to be cleaned?

Answer 1

So first, you have to find how many rooms total there are. If there are 128 rooms on each floor and 4 floors total then you have to do 128 x 4= 512. So, if there are 512 rooms total and 334 are clean already to find how many that need to be cleaned are left you have to subtract 334 from 512.
512 - 334= 178
So, there are 178 rooms left that need to be cleaned.
