10 You can only have one choice, the number 4 as the hundred digit and also one choice, the number 5 as the units digit. However, you can have any integer from 0-9 as the hundreds digit. The number of combinations is thus 1 x 10 x 1 = 10.
The digit after the hundreds digit is 9 which is greater than or equal to 5, so add 1 to the hundreds digit: 14494 → 14500 to the nearest hundred.
There is no one-digit number that is equal to both 14 and 28.
To round 984 to the nearest 100, you need to determine whether the number is closer to 900 or 1000. The tens digit of 984 is 8, which is greater than or equal to 5. Therefore, the ones digit of the rounded number will be 0, and the hundreds digit will be either 9 or 10, depending on whether the number is closer to 900 or 1000. To determine which hundreds digit to use, you can look at the tens and ones digits of the number. Since the tens digit is 8 and the ones digit is 4, the number is closer to 1000 than to 900. Therefore, the hundreds digit of the rounded number will be 9. So, rounding 984 to the nearest 100 gives us 900.
