**A) Express the ratio of rise to run in lowest terms. This ratio describes the slope of the ramp.**

3:12 (simplest terms) 3÷3=1 12÷3=4 1:4

**B) Express the slope ratio as a fraction, a decimal, and a percent.**

**1/4 1÷4= 0.25 25x100%= 25%**

**C) Predict what effect each of the**

**following would have on the slope**

**of the ramp:**

**• increasing the rise**

**• decreasing the rise**

**• increasing the run**

**• decreasing the run**

**When you increase the rise you increase the slope.**

**When you decrease the rise you decrease the slope.**

**When you increase the run you decrease the slope.**

**When you decrease the run you increase the slope.**

**When you increase and decrease in rise, you're moving up and down on the y axis on a grid. When you increase or decrease the run, you're moving left and right on the x axis on a grid.**
