# Estimate the sum of 975 and 778 to the nearest hundred.

- 1200
- 1300
- 1700
- 1800

Hint:

### In the given question first we have to calculate the sum of 975 and 778 then round off the sum to nearest hundreds. For rounding off any number to nearest hundred, look at the tens digit of the number. If the digit is 0,1,2,3 or 4 then the digit at the hundreds place will round down to nearest hundred ,so, the digit at the hundred place would not change. If the digit is 5,6,7,8 or 9 then the digit at the hundreds place will round up to the next number.

## The correct answer is: 1800

### The sum of 975 and 778 = 975+778= 1753.

Conversion of 1753 to nearest hundreds = 1800.
