Question

# Using the front end, estimate the difference of 5430 and 2640.

- 2000
- 3000
- 4000
- 5000

Hint:

### Front-end estimation is a particular way of rounding numbers to estimate sums and differences. To use front- end estimation, add or subtract only the numbers in the greatest place value.

## The correct answer is: 2000

### We have to use frontend estimation to find the difference between 5430 and 2640.

We have 5430 - 2640 = 5000 - 2000 = 3000.

Hence, the correct option is B.

The round off of 5430 is 5000 and round off of 2640 is 2000.
