# Round the following number to $2$ significant digits.$28.5$.

##### SOLUTION
Rounding off a number to the nearest significant digit can be obtained by considering the third digit.
If it is greater than or equal to $5$, then increase the second digit by $1$.

So, the value is $29$.

You're just one step away
