Correct Answer

The next digit, 6, is greater than or equal to 5, so it would round up if necessary. However, since we are rounding to the nearest tenth, there is no need to round up. Therefore, the correct answer is 78.3.Rate this question:

When rounding to the nearest hundred, what is the smallest whole number that will round to 500?
Correct Answer
450Explanation
When rounding to the nearest hundred, we look at the tens digit. If the tens digit is 5 or greater, we round up to the next hundred. If it is less than 5, we round down to the previous hundred. In this case, 450 has a tens digit of 5, so it rounds up to 500. Any number smaller than 450 would have a tens digit less than 5 and would round down to 400.
