Question

Round off:​(iv) $32974$ to the nearest ten- thousand​

Answer 1

Given , number $32974$
So, the thousands digit of $32974$ is $2$.

[If thousands digit is less thgan $5$ , replace each thousand, hundreds, tens and one's digits by $0$ and keep the other digits as they are . Also , if in the given number , thousands digit is $5$ or more than $5$ , increase ten-thousand digit by $1$ and replace each other digit on its right by $0$.
$\because$ $2$ is less than $5$.
So, to round off the given number to the nearest ten-thousand , we replace $2$ (thousand digit ), $9$ (hundreds digit),$7$ (tens digit ) and $4$ (one's digit by $0$.
$\therefore$ $32974$ is $30000$.
Hence, round off of $32974$ to nearest ten- thousand is $30000$.
