In a stairway measuring 8 feet 2 inches with a riser height of 7 inches, how many risers are present?

To determine the number of risers in a stairway, you need to first convert the total height of the stairway from feet and inches to inches only. In this case, the stairway measures 8 feet 2 inches. There are 12 inches in a foot, so:

8 feet = 8 x 12 = 96 inches

Now, adding the additional 2 inches gives:

96 inches + 2 inches = 98 inches total height.

Next, you divide the total height of the stairway by the height of each riser to find the number of risers. Since the riser height is given as 7 inches, the calculation is:

98 inches ÷ 7 inches per riser = 14 risers.

Therefore, the stairway has 14 risers, making this the correct answer. This calculation reflects a practical method used in construction to ensure that stairways are built to standard height for safety and compliance with building codes.
