Final answer:
To round the number 2,767,545 to the nearest ten, we round up because the ones place digit is 5, resulting in the answer 2,767,550.
Step-by-step explanation:
To round the number 2,767,545 to the nearest ten, we look at the digit in the ones place, which is a 5. According to the rules of rounding, if the digit to the right of the rounding place is 5 or equal to 5, you round up. Since the ones place digit is exactly 5, we round the digit in the tens place which is 4, up to 5, resulting in 2,767,550.
It's important to note that in calculations that involve multiple steps, you should avoid rounding off numbers until the final step to maintain accuracy. However, in this simple case, we're only rounding a single number, so we can directly apply the rounding rule.
Another critical aspect of rounding involves the concept of significant figures. For instance, if a number like 2,085.5688 needs to be rounded to five significant figures, the number would be rounded to 2,085.6 because the sixth figure, 5 (in the tenths place), is greater than 5.
