4,320,000,000. Reason: 1. First fine the ten million place..... 2. Look at the next number to the right (3).... 3. If the number is greater than 5 you round up one which is not so you dont round..... 5. Which keeps you at 4,320,000,000..... If you need anymore help feel free to ask me! Hope this helps!

To round to the nearest ten million, you look at the millions digit. In this case, the millions digit is 1, which is less than 5, so you round the number down to 4,320,000,000.
