When we are asked to round a number, we are actually asked to change it to the nearest whole and round number.
When we are asked to round a number, we are actually asked to change it to the nearest whole and round number.
If the ones digit is or higher, we round up to the nearest tens, to the closest larger round number.
If the ones digit is less than , we round down to the nearest tens to the closest smaller round number.
If the tens digit is or higher, we round up to the nearest hundred.
If the tens digit is less than , we round down to the nearest hundred.

To solve this problem, we'll follow these steps:
Let us begin:
Step 1: The number given is 1,852.
Step 2: Decide on rounding to the nearest ten, as indicated by choice scope.
Step 3: Look at the digit in the ones place, which is 2.
Step 4: Given that 2 is less than 5, we do not round up; we round down, leaving the tens digit (5) unchanged.
Step 5: Thus, 1,852 rounded to the nearest ten is 1,850.
Therefore, the solution to the problem is .

To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: The given number is . The relevant digits are the tens digit (2) and the units digit (8).
Step 2: According to the rules for rounding to the nearest ten, if the units digit is 5 or more, we round up the tens digit. Here, the units digit is 8, which is greater than 5, so we add 1 to the tens digit.
Step 3: Rounding up, the tens digit becomes , and the number is rounded to .
Therefore, the solution to the problem is .
Choose the right answer:
To solve the problem of finding the approximation of , follow these steps:
Looking at , examining its digits, the tens place is 3 and the units digit is 3, it is less than 5. Thus, the number rounds down to .
Therefore, rounding to the nearest 10 gives .
\( 52\approx\text{ ?} \)
\( 68\approx\text{ ?} \)
\( 134\approx\text{ ?} \)
\( 1367\approx\text{ ?} \)
\( 465\approx\text{ ?} \)
To solve this problem, we will round the number 52 to the nearest 10. Here's the step-by-step explanation:
Therefore, when 52 is rounded to the nearest 10, it becomes .
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: The tens digit of 68 is 6, and the units digit is 8.
Step 2: Since the units digit (8) is 5 or greater, we round up the number 68.
Step 3: After rounding up, we replace the units digit with 0, resulting in the rounded number 70.
Therefore, the solution to the problem is .
To solve this problem, we'll follow these steps:
Let's proceed through these steps:
Step 1: The number given is . Here, the ones digit is .
Step 2: When rounding to the nearest ten, we consider the rule: if the ones digit is less than , round down; if it is or more, round up.
Step 3: Since the ones digit is , which is less than , we round down. Therefore, we decrease to the nearest ten, which is .
Therefore, the solution to the problem is .
To round the number 1367 to the nearest hundred, we carry out the following steps:
