To round any number, look at the place value you're trying to round to and look at its digit to its right.
If it's bigger than 5, round up and make all the digits to the right 0s.
If not, then simply keep the digit and make all digits to the right 0s.
What digit is in the tenth place value? 5. What is the digit to its right? 6.
6 is greater or equal to 5, so round up and make all the digits to the right 0s.
169.56 => 169.60
So, 169.60 is the answer.
