Answer :
1,139 rounded to the nearest hundred is 1,200. Round up because the tens digit (3) and ones digit (9) warrant it.
To round the number 1,139 to the nearest hundred, we look at the tens and ones digits. In this case, the tens digit is 3, and the ones digit is 9.
1. Identify the rounding digit: The rounding digit is in the tens place, which is 3.
2. Look at the digit to the right (ones digit): The ones digit is 9.
3. If the ones digit is 5 or greater, round up; if it's less than 5, round down: In this case, the ones digit (9) is greater than 5, so we round up.
4. Change the tens and ones digits to zero: After rounding up, change the tens and ones digits to zero.
Now, let's apply these steps:
The tens digit is 3.
The ones digit is 9 (which is greater than 5).
So, rounding up, we change 1,139 to 1,200. Therefore, 1,139 rounded to the nearest hundred is 1,200.
In conclusion, the process involves identifying the rounding digit, examining the digit to the right, determining whether to round up or down, and adjusting the number accordingly. In this case, rounding 1,139 to the nearest hundred results in 1,200.
