The title of our math book is: Xiaoping's building has 15 floors, and Xiaoping lives on the seventh floor. How high is the floor of Xiaoping's house from the ground?

Solution: The question is about the height of the "floor from the ground", so the floor of Xiaoping's house is 6 floors from the ground, and then multiplied by 6 times the height of each floor, the answer comes out.

Formula: 50÷ 15×(7- 1)

= 50/ 15 ×6

=20 meters

A: Xiaoping's floor is 20 meters from the ground.
