Question 916675
Find the slope (or PITCH) of the roof.

Rise: 2 ft 5 in.
Run: 8 ft 2 in


----------------------------------------------------------------------------------
----------------------------------------------------------------------------------


2 ft 5 in = 2 ft + 5 in = 2 ft + 5/12 ft = 2 + 5/12


2 + 5/12 = 24/12 + 5/12 = (24 + 5)/12 = 29/12


2 ft 5 in = 29/12 ft


-------------------------------------------------------


8 ft 2 in = 8 ft + 2 in = 8 ft + 2/12 ft


8 + 2/12 = 96/12 + 2/12 = (96 + 2)/12 = 98/12


8 ft 2 in = 98/12 ft


-------------------------------------------------------


Rise: 29/12 ft


Run: 98/12 ft


-------------------------------------------------------


Divide the rise by the run to get the slope or pitch


Slope = Rise/Run


Slope = (29/12)/(98/12)


Slope = (29/12)*(12/98)


Slope = (29/1)*(1/98)


Slope = 29/98


The slope as a fraction is 29/98


29/98 = 0.295918


The slope as a decimal number is approximately 0.295918
