How do you round a repeating decimal to the nearest hundredth

You would round it like any other decimal number to the nearest hundredth by referring to the thousandths place. If the thousands place is 5 to 9, you would round the hundredths place up by one and cut any remaining values to the right of it. If the thousands place is 0 to 4, you would leave the hundredths place at the value it is and cut any remaining values to the right of it.

Examples:

13.374848 rounds to 13.37

12.1792 rounds to 12.18
