Answer

20 lawns\text{20 lawns}

Step-by-step solution

2 steps
  1. Determine the rate of mowing lawns per hour.

    The rate is the number of lawns mowed divided by the time taken.

    Rate=Number of lawnsTime taken=4 lawns7 hours\text{Rate} = \frac{\text{Number of lawns}}{\text{Time taken}} = \frac{4 \text{ lawns}}{7 \text{ hours}}
  2. Calculate how many lawns can be mowed in 35 hours using the rate.

    Multiply the rate by the new time.

    Number of lawns=Rate×New time\text{Number of lawns} = \text{Rate} \times \text{New time} Number of lawns=4 lawns7 hours×35 hours\text{Number of lawns} = \frac{4 \text{ lawns}}{7 \text{ hours}} \times 35 \text{ hours} Number of lawns=4×357 lawns\text{Number of lawns} = \frac{4 \times 35}{7} \text{ lawns} Number of lawns=4×5 lawns\text{Number of lawns} = 4 \times 5 \text{ lawns} Number of lawns=20 lawns\text{Number of lawns} = \boxed{\text{20 lawns}}
