The Alaska quake of 1964 measured 9.2 on the Richter scale, and the Sri Lanka quake of 2004 measured 9.0. How many times more intense was the Alaska quake (rounded to the nearest hundredth)?

This is a multiple choice question on the practice exam I'm studying to get ready for an Advanced Math 12 Regional exam. I got it wrong and I have absolutely know idea how, it seems like such a simple problem! I'm most likely just over-thinking it. The answer key says that the answer should be 1.58. Can anyone show me how to do it?
