How many units are there on each floor if a building has a total of 28 two-bedroom units across 4 floors?

To find the number of units on each floor, you need to divide the total number of units by the total number of floors. In this case, the building has 28 two-bedroom units distributed across 4 floors.

When you perform the calculation:

28 units ÷ 4 floors = 7 units per floor.

This means that each floor of the building contains 7 two-bedroom units, making the answer correct. Understanding this division represents a fundamental concept in basic arithmetic, which is essential in architectural planning and resource allocation.
