Question

Round off

$4.5678$to $3$ decimal places.

Answer 1

Rounding decimals to the given decimal places

We retain $3$ decimal digits in $4.5678$ to get $4.567$

The next digit to the right of the last retained digit is $8$, which is greater than $5$.

So, we increase the last retained digit by $1$.

$\therefore$ Required number = $4.568$
