Question

Round off $357$ to nearest ten

Answer 1

Rounding off to nearest ten

To round off in tens-

(i) Look at the digit right to tens place. If the digit is less than $5$ leave the digit in tens place as it is. If the digit is $5$ or more than $5$. Then add $1$ to the tens place.

(ii) Change all the digits to the right of the tens place to $0$

We have, $357$ in which digit after tens place is $7$.

As $7>5$, adding $1$to the tens place and replacing all the digits right of place to $0$.

Hence, rounding off of $357$ to nearest ten is $360$
