Answer:

1.04 inch

Step-by-step explanation:

Given: Old house has a basement stairways with 7.25 inch vertical riser and 7 inch horizontal treads.

Remember; horizontal treads is known as run in steps.

Now, calculating the slope of the stairways.

Formula: $Slope= \frac{Rise}{Run}$

Rise= 7.25 inch

Run= 7 inch.

Subtituting the value in the formula

Slope= $\frac{7.25}{7}= 1.0357 \approx 1.04$ (∵ Round to two decimal)

∴ Slope of stairways is 1.04.
