When estimating division problems, rounding will not work very well. You must use compatible numberscompatible numbers.
Compatible numbers Compatible numbers are numbers that contain a basic division fact…
…8,100 ÷90, 720 ÷ 8, 144,000 ÷ 120
Step 1: Look at the first couple of numbers of the dividend and the first number of the divisor.
Step 2: Find the closest basic division fact to these numbers
Step 3: Use the basic fact to change the dividend and divisor to compatible numbers, and divide.
