Ajet airplanes hose about 65,000 gallons of gas he uses about 7460 gallons when flying between new york city and los angeles. round each number to the largest place value then find about how many trips the plane can take between cities before running out of fuel

8 trips

Explanation:

Rounding to the largest place value of 7,460 is 7,000
Considering 7 * 5 = 35, and 35 * 2 = 70 (you can scale up the problem to the thousands such as 70 * 50 = 3,500, etc) so since 7 * 10,000 is 70,000 we can estimate that the plane driver can take about 8 trips (70,000 - 7,000, or 1 trip then we account for the extra 460 gallons for each trip then we just take off one more trip.)
