Final answer:
To round 3,137 to the nearest hundred, look at the tens digit. Since it is 3 (less than 5), the rounded number is 3,100.
Step-by-step explanation:
To round 3,137 to the nearest hundred, we need to look at the tens digit, which is 3. Since this number is less than 5, we do not round up the hundreds place. Therefore, 3,137 rounded to the nearest hundred is 3,100.
When performing rounding, it's essential to identify the digit at the place value you are rounding to and then look to the immediate right to decide whether to round up or down. As the tens place in 3,137 has a 3, which is less than 5, we keep the hundreds place as it is.
This concept of rounding is very useful in various mathematical applications and helps in simplifying numbers for estimation or reporting purposes.
