If the rise of a roof is 8 feet and the run is 2 feet 8 inches, what is the pitch of the roof in lowest terms when written as a FRACTION?
8 feet = 96 inches
2 feet 8 inches = 24+8= 32
so is it 32/96
which equals 1/3

Rise is always divided by the run.
Rise/Run is what you must use.
However, the rise is 96 inches in this case and the run is 32 inches.
So, our fraction should be 96/32 = 3.
However, 3 is a whole number not a fraction.
Is there a typo here?
Shouldn't the rise be 32 and the run 96? Go back and check your question.
If the rise is 32 and the run 96, then the answer is 1/3.
But keep in mind that the correct way to express the fraction in terms of rise and run is rise/run and not run/rise.
Write back.
Yes, you are correct. The pitch of the roof can be expressed as a fraction by dividing the rise (8 feet or 96 inches) by the run (2 feet 8 inches or 32 inches).
Since both the rise and the run are in inches, you can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 32 in this case.
Dividing both 32 and 96 by 32, you get:
32 ÷ 32 = 1
96 ÷ 32 = 3
Therefore, the pitch of the roof, when expressed as a fraction in lowest terms, is 1/3.
