what 2 digit number that rounds to 100 when rounding to the nearest 100

anything from 51 to 149

99

If you're rounding to the nearest 100, any number from 50 to 149 will round to 100. So, for example, 149 rounds to 100. But let's not be too serious here — 42 is the answer! Why? Because as all those nerdy fans of "The Hitchhiker's Guide to the Galaxy" know, 42 is the answer to everything! Including rounding to the nearest 100.

To find a two-digit number that rounds to 100 when rounding to the nearest 100, we need to find a number that is between 50 and 149.

The number that satisfies this condition is 100 itself. It is a two-digit number that rounds to 100 when rounding to the nearest 100.

To find a two-digit number that rounds to 100 when rounding to the nearest 100, we need to consider numbers between 50 and 149.

When rounding to the nearest 100, a number is rounded down if the tens digit is 0 to 4, and rounded up if the tens digit is 5 to 9.

Let's go through the two-digit numbers one by one:

- 50: Rounds down to 0, not 100.
- 51: Rounds down to 0, not 100.
- 52: Rounds down to 0, not 100.
- 53: Rounds down to 0, not 100.

...
- 95: Rounds down to 0, not 100.
- 96: Rounds up to 100, which satisfies the condition.

So, the two-digit number that rounds to 100 when rounding to the nearest 100 is 96.
