Question

16. A building has more than 2 stories but fewer than 10 stories. Each story of the building has the same number of windows. The. building has 25 windows. Complete the sentence. Then explain how you found your answer.

Answer 1

The building has 5 stories.

To find the number of stories in the building, we need to find the number of stories that would result in a total of 25 windows. Since each story has the same number of windows, we can divide the total number of windows by the number of windows per story to find the number of stories.

For example, if there are 2 stories and each story has 12 windows, then the total number of windows would be 2 * 12 = 24 windows. This is too few windows, so we need to try a higher number of stories.

If there are 3 stories and each story has 8 windows, then the total number of windows would be 3 * 8 = 24 windows. This is still too few windows, so we need to try a higher number of stories.

If there are 4 stories and each story has 6 windows, then the total number of windows would be 4 * 6 = 24 windows. This is still too few windows, so we need to try a higher number of stories.

If there are 5 stories and each story has 5 windows, then the total number of windows would be 5 * 5 = 25 windows. This is exactly the right number of windows, so we have found the solution.

Therefore, the building has 5 stories.
