Rounding anything to the nearest hundred, means finding out if the hundred above is nearer or further than the hundred below. As you go up from 40 the 1st hundred you get to is 100. As you go down then the first one is zero hundred (that is, zero). The 100 is 60 higher, and the zero is 40 lower so that is nearest. So the answer is 0.

To round 97 to the nearest 100, you need to look at the digit in the tens place, which is 9 in this case. Since 9 is greater than or equal to 5, you will round up. Therefore, 97 rounded to the nearest 100 is 100.

2.8735 to the nearest tenth is 2.9.
100
It is 800 because 40 is less than 50
To round 165 to the nearest hundred, you consider if 65 is closer to 0 or to 100. Since 65 rounds up to 100, 165 would round up to 200. In contrast, if the question had been to round 140 to the nearest hundred, 40 would round down to zero, so the answer would have been 100.
372 rounded to the nearest hundred is 400
It depends how round you want it.-- To the nearest 1/10th or to the nearest unit: 42-- To the nearest 10: 40-- To the nearest 100: Zero
