Question

How do you round 328 to the nearest hundred?

Answer 1

Hint: When rounding to the nearest hundred, we use the following rules:
We round the number up to the nearest hundred if the last two digits in the number are 50 and above.
We round the number down to the nearest hundred if the last two digits in the number are 49 or below.
If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.

Complete step-by-step answer:
In this question, we want to round 328 to the nearest hundred.
For that, we will check the last two digits in the number.
The last two digits in the number are 28.
The number 28 is below 50.
Therefore, we round the number down to the nearest hundred.
Here, the number is 328 and the number down to the nearest hundred is 300.

Hence, the answer is 300.

Note:
We can say that if the number is below 350 then we round the number down to the nearest hundred. Therefore, the answer will be 300.
If the number is above 350, then we round the number up to the nearest hundred. Therefore, the answer will be 400.
The purpose for rounding to the nearest value:
Making calculations easy
Making the numbers easy to understand and remember.
Application of rounding:
Estimation: We use rounding to guess the most appropriate answer. Rounding is the process of estimation. Estimation helps us to calculate easily.
