Answer: Using compatible numbers can help estimate the solution to many problems. In this case, the equation is 37x24. Compatible numbers are anything that is a multiple of 5. For example, 5, 10, 15, 20, etc. Rounding 37, to 35, and 24 to 25, you can multiply. Whatever you get, can infer what the answer or the answer range is.
