Question

How do you round $ 3,779 $ to the nearest hundred?

Answer 1

Hint: In order to round a given number to nearest hundred, see the number at ten’s place whether it is greater than or less than the number $ 5 $ and do as follows:
If greater than $ 5 $ then increase the number at hundredth place by $ 1 $ and put zeroes following it at ten’s and one’s place.
If the number is less than $ 5 $ then leave the number at hundredth place as it is and put zeroes following it at ten’s and one’s place.

Complete step-by-step answer:
To round off the given number $ 3,779 $ to the nearest hundred, we will first see at the ten’s place of the number whether it is greater or less than $ 5 $
In the number $ 3,779 $ ,
 $ 7 $ is the digit at ten’s place and we know that it is greater than $ 5 $
So now $ 7 $ is greater than $ 5 $ , we will increase the digit at hundredth place by $ 1 $
We can see that in the number $ 3,779 $
 $ 7 $ is the digit at hundredth place, so increasing it by $ 1 $ we will get
 $ 7 + 1 = 8 $
Now writing $ 8 $ in the hundredth place of the given number and putting zeroes at ten’s and one’s place following $ 8 = 3,800 $
So the required rounded number of $ 3,779 $ to the nearest hundred is $ 3,800 $
So, the correct answer is “ $ 3,800 $ ”.

Note: Rounding off a number when the figure dropped is $ 5 $ have different cases, that is if there is only $ 0's $ after $ 5 $ then we will see the number which is to be rounded if it is odd then increase it by one or if it is even then left it as it is. And if there is any digit present after $ 5 $ except $ 0 $ then simply increase the number by $ 1 $
