The area of a rectangular banquet hall is 7,400 square feet. The length of one side of the hall is 82 feet. EXPLAIN how you can use compatible numbers to estimate the width of the hall.
(Answers will vary)
If I change the numbers to be compatible, it will be easier for me to estimate in my head.
7,400 --> 7,200
82 --> 80
I chose 7,200 and 80 because I can divide those numbers in my head. Take one zero away from each number and you get 720 ÷ 8. If I imagine the zero not there, I can divide 72 by 8 easily (9). Then I put the zero onto the 9 for an estimate of 90.
