Question

Round the number to the nearest tens : $64$

Answer 1

Given, number is $64$.

For rounding off to nearest tens,we first check the digit at one's place.If the digit at one's place is less than $5$ then we replace it by zero but the digit at one's place is $\ge 5$ then we add $1$ to ten's place digit and replace one's place by zero.

Here one's place is $4<5$.

So, $64\to 60$.

Hence, the nearest tens round off of $64$ is $60$.
