Subtract the difference in the days from the number of yards.
Find the number of yards per day by division, and then multiply that quotient by the number of days.
Find the number of yards per day by division, and then divide that quotient by the number of days.

Answer 1

To determine how many yards Nima can mow in 20 days, the best strategy is:

Find the number of yards per day by division, and then multiply that quotient by the number of days.

Here's how you can work it out:

1. First, find out how many yards Nima mows per day. Since Nima can mow 18 yards in 6 days, you can calculate the yards per day by dividing: \[ \text{Yards per day} = \frac{18 \text{ yards}}{6 \text{ days}} = 3 \text{ yards per day} \]

2. Next, to find out how many yards Nima can mow in 20 days, you multiply the yards per day by the number of days: \[ \text{Yards in 20 days} = 3 \text{ yards per day} \times 20 \text{ days} = 60 \text{ yards} \]

Thus, Nima can mow 60 yards in 20 days using this approach.
