349 plus 252 round each number the greatest place value
300+300
To round each number to the greatest place value, follow these steps:
1. Identify the greatest place value in each number. In this case, both numbers have the same greatest place value, which is the hundreds place value.
2. Look at the digit in the next place to the right of the greatest place value. For example, in 349, the next place value to the right of the hundreds is the tens place, and in 252, the next place value to the right of the hundreds is also the tens place.
3. If the digit in the next place value is 5 or greater, add 1 to the digit in the greatest place value and replace all digits to the right of it with zeros. If the digit in the next place value is less than 5, simply replace all digits to the right of the greatest place value with zeros, without changing the digit in the greatest place value.
Now let's apply these steps to your example:
Step 1: Both numbers have the greatest place value in the hundreds place.
Step 2: Look at the digit in the next place value:
- In 349, the digit in the tens place is 4.
- In 252, the digit in the tens place is 5.
Step 3: Now let's apply the rounding rules:
- For 349, the digit in the tens place is less than 5. Therefore, we keep the digit in the hundreds place (3) and replace all digits to the right with zeros. So, rounded to the greatest place value, 349 remains as 300.
- For 252, the digit in the tens place is 5, which is greater than or equal to 5. Therefore, we add 1 to the digit in the hundreds place (2), resulting in 3. We then replace all digits to the right with zeros. So, rounded to the greatest place value, 252 becomes 300.
As a result, rounding 349 and 252 to the greatest place value results in both numbers being 300.
