Answer: 114,510,000
Delete the commas if needed.
============================================
Step-by-step explanation:
The given number is 114,509,772
The 0 is in the ten thousandths place value. Just to the right of it is 9, which fits the criteria of "5 or larger". So we'll bump the "509" up to "510". Everything to the right of 9 will be replaced with zeros.
That's how we go from 114,509,772 to 114,510,000
-------------
Put another way:
Temporarily ignore the 114 up front and focus on the remaining portion 509,772
This number can be verbalized as "509 thousand" in an approximate sense. The 772 at the end means it's much closer to 510 thousand than it is to 509 thousand. That's why the 509 bumps up to 510.
Therefore, we have 509,772 round to 510,000
Overall, we have 114,509,772 round to 114,510,000
