# How do you round 3,876 to the nearest hundred?

Oct 26, 2016

$3 , 876$ rounded to the nearest hundred is $3 , 900$.
See Explanation.

#### Explanation:

We have the number $3 , 876$ and we want to round it to the nearest hundred.

In order to round it to the nearest hundred, though, let's go over some rules...
1) If the number is more than $50$, then you round up. If the number is less than $50$, then you round down.

In this case, the $76$ in $3 , 876$ is more than $50$, so $3 , 876$
rounded to the nearest hundred is $3 , 900$

Hope this helps!

$3876 \text{ is "3900" to the nearest 100}$

#### Explanation:

$\textcolor{b l u e}{\text{The digit of 8 is that of the hundreds. So the 'cut off point' is to its}}$ $\textcolor{b l u e}{\text{right. }}$

If the digit to the right of the cut of point is 5 or more we round up the 8 by 1. If the digit to the right of the cut off point is less than 5 we do not change the 8

$\textcolor{w h i t e}{.} 38 \textcolor{red}{|} 76$
$\textcolor{w h i t e}{\ldots .} \textcolor{red}{\uparrow}$
$\textcolor{red}{\text{Cut off point}}$

7 fits the description '5 or more' so we change the 8 into 9 and all the numbers to the right of the cut off point become 0.

$3876 \text{ is "3900" to the nearest 100}$
