Question

ethan mowed 4 lawns in 6 hours. what was his rate of mowing in lawns per hour? resize the right columns to represent the unit rate.

Explanation:

Step1: Identify the formula for rate

Rate is calculated as the number of lawns divided by the number of hours. So the formula is \( \text{Rate} = \frac{\text{Number of Lawns}}{\text{Number of Hours}} \).

Step2: Substitute the given values

We know the number of lawns is 4 and the number of hours is 6. Substituting these values into the formula, we get \( \text{Rate} = \frac{4}{6} \).

Step3: Simplify the fraction

Simplify \( \frac{4}{6} \) by dividing both the numerator and the denominator by their greatest common divisor, which is 2. So \( \frac{4\div2}{6\div2} = \frac{2}{3} \).

Answer:

\( \frac{2}{3} \) lawns per hour
