Question

Ned calculated 17 divided by 4= 4.25. Use estimation to see if his answer is reasonable. How can you check his exact answer?

Answer 1

Answer:

you can use estimation by saying that 4 * 4 = 16 and 4 * 5 = 20

therefore your number has to be less that 5 but slightly greater than 4.

you can check his exact answer by doing division or checking it on a calculator.
