Round off numbers

Rounding off means a number is made simpler by keeping its value intact but closer to the next number

Round the number to the nearest hundreds.

Example:

Step1: Underline the number in the 'hundreds' place value.

3	2	6
Hundreds	Tens	Ones

Step 2: Identify the number for 'tens'.

Weak Numbers

Strong Numbers

Digits in the 'hundreds' place value Digits in the 'hundreds' place value

add 0 add 1

\(\begin{aligned} &\color{red}{3}\;2\;6\quad\Longrightarrow\quad\;\color{red}{3}\;2\;6 \\&\small{+0} \end{aligned}\)

2 is in 'weak numbers',

so the number in the hundreds place must add 0.

Step 3: Change the number in the 'tens' and 'ones' place value to zero.

\(3\;\color{red}{2}\;\color{red}{6}\quad\Longrightarrow\quad3\;\color{red}{0}\;\color{red}{0}\)

So, 326 rounded to the nearest hundreds is 300.
