Round $54.\overline{54}$ to the nearest hundredth.
Rounding a repeating decimal to the nearest hundredth requires me to look at the third decimal place after the decimal point, since that will determine whether I round up or down. In this case, the third decimal place is a 5, which means I round up. To round up, I increase the second decimal place by one and drop the rest of the decimals. So the final answer is 54.55.
