It rounds down because the number in the hundredths is less than 5. The rule is: If the number is ≥ 5 then you round up.
The answer is 290
If you are rounding to the nearest whole number, 29.35 would round down to 29. If you are rounding to the nearest 5 or the nearest 10, it would round up to 30.
To round 294 to the nearest hundred, we look at the digit in the tens place, which is 9. Since 9 is greater than or equal to 5, we round up the hundreds place by 1. Therefore, 294 rounded to the nearest hundred is 300.
