Answer:
4800
Explanation:
4773
The 3 is the ones digit.
The 7 to the left of the 3 is the 10s digit.
The 7 (in bold) to the left of the other 7 is the hundreds digit.
1. Make all digits to the right of the hundreds digit 0.
4700
2. We need to find out if we end up with 4700 or 4800.
Since the digit just to the right of the hundreds digit is greater than 4 (it is the tens digit which is a 7), then the hundreds digit 7 must go up 1 to 8.
Answer: 4800
