    They started with the notion that 180 degrees = ##\pi## radians

    and then the equivalent notion that 10800 minutes = ##\pi## radians

    and then they construct a ratio 180 deg / (18 deg 30 min) = (10800 min) / (1100 min) = 360 / 37 = ##\pi## / x radians

    and then solve for x.

    My question is to simplify,
    how do I simplify? Method of successive division! si.png m.png

    Simplify what?
    I don't see anywhere in your thread what it is you're trying to do.
    Is the problem to convert 18° 30' into minutes? Or is it to convert this angle measure to radians?

    I'm trying to understand the simplification,
    should be 30 to 10800 and 30 to 1110 ,lol
    Thank you for letting me know

    You didn't answer my question. What are you trying to convert?

    Is your question how they went from ##\frac{10800}{1110}## to ##\frac{360}{37}##? If so, 1080 = 30 * 360, and 1110 = 30 * 37.

    Perfect is 30
