What is 448 rounded to the nearest tens?

Answers

Here we will tell you what 448 is rounded to the nearest ten and also show you what rules we used to get to the answer. First, 448 rounded to the nearest ten is:
When rounding to the nearest ten, like we did with 448 above, we use the following rules:

A) We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.

B) We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.

C) If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.

What is 449 rounded to the nearest ten?
Now you know what 448 rounded to the nearest ten is. Go here for the next number we rounded.

When 448 is rounded to the nearest tens then the value is 450.

When rounding a number to the nearest tens, we consider the digit in the tens place.

In the case of 448, the digit in the tens place is 4.

To round to the nearest tens, we examine the digit in the ones place, which is 8. Since 8 is greater than or equal to 5, we round the tens place up by 1.

Therefore, the digit in the tens place becomes 5, and all the digits to the right of the tens place become zeros.

This gives us the rounded value of 450.
