Question

Round off the following number to the nearest tens: $13$

Answer 1

Rounding off to the nearest tens

First, check the ones place digit of the given number.

Here, the ones place digit of $13$ is $3$

According to the rounding off to nearest ten rule,

• If ones place digit is less than $5$, replace the ones digit by $0$ and keep other digits same.
• If ones place digit is equal to or greater than 5, replace the ones digit by $0$ and increase the tens digit by $1$ keeping other digits same.

Since, $3<5$, the ones digit is replaced by $0$ and tens digit will remain same.

So, $13$ rounded off to the nearest tens is $10$.

Hence, $13$ rounded off to the nearest tens is $10$.
