if these aren't correct show me how to work these ?
The first answer is correct.
Estimate 15.264-8.12 by first rounding each number to the nearest tenth.
15.3 - 8.1 = 7.2

To round 0.575 to the nearest hundredth, we look at the digit in the thousandth place, which is 5. Since 5 is greater than or equal to 5, we round up the digit in the hundredth place, which is 7. Therefore, 0.575 rounded to the nearest hundredth is 0.58, not 0.60.
To estimate 15.264 - 8.12 by first rounding each number to the nearest tenth, we look at the digit in the hundredth place of each number.
For 15.264, the digit in the hundredth place is 6, which is greater than or equal to 5. So, we round up the digit in the tenths place. Therefore, 15.264 rounded to the nearest tenth is 15.3.
For 8.12, the digit in the hundredth place is 2, which is less than 5. So, we leave the digit in the tenths place as it is. Therefore, 8.12 rounded to the nearest tenth is 8.1.
Now, we can subtract the rounded numbers: 15.3 - 8.1 = 7.2
So, the correct answers are:
- Round of 0.575 to the nearest hundredth is 0.58.
- Estimate 15.264 - 8.12 is 7.2.
To round a number to the nearest hundredth, you look at the digit in the thousandth place. If that digit is 5 or above, you round the number up. If it is less than 5, you round the number down.
For example, to round 0.575 to the nearest hundredth:
- The digit in the thousandth place is 5, which is equal to 5, so we round up.
- The next decimal place, the hundredth place, becomes 6.
- Therefore, rounding 0.575 to the nearest hundredth gives us 0.58, not 0.60.
Now let's move on to the second question:
To estimate the subtraction of 15.264 and 8.12 by first rounding each number to the nearest tenth, you would follow these steps:
1. Look at the digit in the hundredth place. For 15.264, it is 4.
- Since 4 is less than 5, we round this digit down to 0.
- The number becomes 15.260 (rounded to the nearest tenth).
2. Similarly, for 8.12, the digit in the hundredth place is 1.
- Since 1 is less than 5, we round this digit down to 0.
- The number becomes 8.10 (rounded to the nearest tenth).
Now you can subtract the rounded numbers: 15.260 - 8.10 = 7.160
So, the answer is 7.160.
