Fist break up each number in the hundreds column add the tens and the ones then add the hundreds to the previous answer
It would be 20 percent, I believe. First you would put it into a fraction of 12\60, then you would simplify that into 3\15 then divide as shown. You end up with .2 which would be 20 percent.

2x=50
x=25°
