# The difference of 587 and 222 using front -end estimation is ________.

- 200
- 300
- 400
- 500

Hint:

### We have to find the difference of 587 and 222 using front end estimation. Firstly we will round off both number to nearest highest number place, in this question we will round off to nearest hundred. Further we will subtract the numbers and will get the required number i.e. the estimated difference of 587 and 222.

## The correct answer is: 400

### Rounding off 587 = 600

Rounding off 222= 200

difference between these numbers

=600-200

=400

So, the difference of 587 and 222 using front end estimation is 400.
