Rounding off to nearest tenths
Round off $0.2545$ to nearest tenths. Following my instinct, the answer is $0.3$ because that's what it is more close to. Following the rules, as told by my teacher, it comes out to be $0.2$. Steps I followed while I rounded it as $0.2000$:
- Last digit of $0.2545$ is $5$ and the preceding digit is $4$-even, so I write it as $0.254$
2.Now, in $0.254$, last non-zero digit is $4$ , so it gets converted to $0.25$
3.In $0.25$ last non-zero digit is $5$ and the digit preceding $5$ is $2$, even no. So, $0.25$ gets converted to $0.2$
Which is right answer?

$\begingroup$To round to the "nearest" tenth, look at the hundredths place. If it is $5$ or more, round up. Otherwise, round down.
In this case, since we have $5$ hundredths, then it rounds up to $0.3.$
Edit: Based on your link, by Rule 2, we look at the hundredths, and seeing a $5,$ we round up, giving us $0.3$
