Let's analyze the information step by step:

1. **Rounded to the nearest 10, her number is 650**: This implies the number could be anywhere between 645 and 654, since these are the numbers that round to 650 when rounding to the nearest 10.

2. **Rounded to the nearest 100, her number is 700**: This means the number must be between 650 and 749, since those numbers round to 700 when rounded to the nearest 100.

3. **Her number is odd**: This narrows down the possible values. The odd numbers between 645 and 654 are 645, 647, 649, 651, and 653.

4. **Intersection of conditions**: For the number to satisfy all the conditions, it must be:
   - Between 645 and 654 (from rounding to 650).
   - Between 650 and 749 (from rounding to 700).
   - Odd.

Thus, the only number that satisfies **all three conditions** is **651**.

Tina's number is **651**.

Would you like a more detailed breakdown, or do you have any additional questions?

Here are 5 related questions to extend your learning:
1. What would the number be if it were even, given the same conditions?
2. How is rounding to the nearest 100 different from rounding to the nearest 10 in general?
3. Can you explain how rounding affects a number when it is closer to a midpoint, like 650?
4. What would the range of possible numbers be if the nearest 100 rounding condition changed to 600?
5. Can you think of another example where a number fits multiple rounding conditions like this one?

**Tip**: When rounding, numbers ending in 5 are rounded up when rounding to the nearest 10 or 100.

Tina thinks of a whole number. Rounded to the nearest 10, her number is 650. Rounded to the nearest 100, her number is 700. Her number is odd. What could her number be?

In this math problem, Tina thinks of a whole number that rounds to 650 when rounded to the nearest 10 and to 700 when rounded to the nearest 100. Learn how to determine the correct number based on rounding rules and the fact that the number is odd.
