Explanation:

Step1: Define rate formula

Rate = $\frac{\text{Total Hours}}{\text{Total Lawns}}$

Step2: Plug in given values

Rate = $\frac{9}{12}$

Step3: Simplify the fraction

$\frac{9}{12} = \frac{3}{4}$

Answer:

$\frac{3}{4}$ hours per lawn

For the bar graph:

• The "1 lawn" column (purple) should be resized to a height of 1.
• The "hours per lawn" column (green) should be resized to a height of $\frac{3}{4}$ (or 0.75).
