Question

Round off the following number to the nearest tens: $55$

Answer 1

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

Here, the ones place digit of $55$ is $5$

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, $5⩾5$, the ones digit is replaced by $0$ and tens digit is increased by $1$.

So, $55$ rounded off to the nearest tens is $60$.

Hence, $55$rounded off to the nearest tens is $60$.
