Answer
The smallest possible number of pupils is 700.
Solution
To find the smallest possible number of pupils that attend the school when rounded to the nearest 100, we need to consider the rounding rules.
When rounding to the nearest 100, we look at the tens digit of the number. If the tens digit is 5 or greater, we round up. If the tens digit is 4 or less, we round down.
Since we are looking for the smallest possible number, we want to round down. The number 800 has a tens digit of 0, which is less than 5, so we would round down to the nearest 100.
Rounding down from 800 to the nearest 100 gives us 700.
Therefore, the smallest possible number of pupils that attend the school, when rounded to the nearest 100, is 700.

Simplify this solution Beyond the Answer
The smallest possible number of pupils that could be rounded to 800 when rounding to the nearest hundred is 750. This is because any number from 750 to 849 will round to 800 when you apply the rule of rounding. On the flip side, if we were considering a scenario with a larger rounding base, such as rounding to the nearest thousand, the smallest possible number that would still round to a specified figure could dramatically change the outcome. In this case, for rounding to 800, you merely need to focus on that nearest hundred, but keep in mind how different rules apply to varying situations!
