Aarons wants to plant an herb garden that is $1 \frac{1}{2}$ yards long and has an area of 5 square yards. How wide should the garden be?

Step 1 ：Aaron wants to plant an herb garden that is \(1 \frac{1}{2}\) yards long and has an area of 5 square yards. We need to find out how wide the garden should be.

Step 2 ：We can find the width of the garden by dividing the area by the length. The area is 5 square yards and the length is \(1 \frac{1}{2}\) yards.

Step 3 ：Let's calculate the width by dividing the area by the length: \( \frac{5}{1.5} \approx 3.33 \)

Step 4 ：The width of the garden should be approximately 3.33 yards. This is the result of dividing the area of the garden (5 square yards) by its length (\(1 \frac{1}{2}\) yards).

Step 5 ：\(\boxed{3.33}\) yards is the final answer. This is the width of the garden.
