The following is an example that shows how to do Estimation Division for the problem 727 / 3. 1. First write the problem as shown. 2. Draw a line down the side. 3. Beginning with multiples of 10, estimate how many times 3 goes into 727 without going over.
7. Multiply 3 X 100 and subtract that from 427.
9. Multiply 3 X 40 and subtract that from 127. 10. Estimate how many times you can divide 7 by 3. 11. Multiply 3 X 2 and subtract that from 7. 12. Add all the numbers along the right side which should be 100,100,40 and 2. 13.Write that number down below the right side line.
