Answer:
4,278,649 rounded to the nearest hundred is 4,278,600.
Step-by-step explanation:
If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. So, since the 6 is in the hundreds place, having the value of 600 and since you rounded to the hundreds place, the numbers to its right turn into 0s. They do not go away.
