M makinsushi Dec 2009 1 0 Dec 9, 2009 #1 I'm learning about degrees and radians and this came up in my homework. Convert: Example: 54(degrees)45(minutes) to decimal degree form. I know (after using the DMS function on my calculator) that the answer is 54.75 How do I do this without my calculator? How do I convert DMS back and forth?

How do I convert DMS back and forth? Click to expand... use the DD conversion (to get the decimal degrees) be sure that mode set to approximate with TI-89 anyway Last edited: Dec 9, 2009

J jgv115 Jul 2009 275 43 Melbourne Dec 10, 2009 #3 The OP said to do it without a calculator. We have 54 and 45 minutes. We have to convert into decimal. How many minutes in a degree? 60. So \(\displaystyle \frac {45}{60} \) \(\displaystyle = 3/4 \) \(\displaystyle = 0.75 \) So that's how you get 54.75
