Final answer:
To estimate the value of 197 + 10.3 by rounding each number to the nearest 10
Explanation:
To round the numbers to the nearest 10, look at the digit in the ones place. If the digit is 0-4, the number rounds down. If the digit is 5-9, the number rounds up.
- Rounding 12 to the nearest 10: The ones digit is 2, which is less than 5, so it rounds down to 10.
- Rounding 93 to the nearest 10: The ones digit is 3, which is less than 5, so it rounds down to 90.
Now, we have 10/90, which simplifies to 1/9. So the estimated value of 197 + 10.3 is approximately 197.1.
