Question # 22

a) Express the ratio of rise to run in lowest terms.

• Rise : Run
• 3 : 12
• 1 : 4

b) Express it as a fraction, decimal, and percent.

• Fraction - 1/4
• Decimal - 0.25
• Percent - 25 %

c) Predict what effect each of the following would have on the slope of the ramp:

• increasing the rise - If the rise increased by 1, it would change the lowest term fraction into 1/3 instead of 1/4.
  
• decreasing the rise - If the rise decreased by 1, it would change the lowest term fraction into 1/6 instead of 1/4.
  
• increasing the run- If you increase the run, then the rise would be increased too.
  
• decreasing the run- If you decrease the run, then the rise would be decreased also.
