Question
The estimated value of 420 ÷ 21 is ________.
The estimated value of 420 ÷ 21 is ________.
- 20
- 21
- 25
- 15
Hint:
420÷21
Using 21 table we can solve the problem.
The correct answer is: 21
420÷21
Estimate:
* 420÷21 will be close to 420÷20, which is 21.
The remainder when 420 is divided by 21 is 0.
Therefore the quotient and answer is 20.
