1/6(36 + 1/2) = 6 + 1/12 = 72/12 + 1/12 = 73/12
Since a whole rotation is 360 degrees, you can take the whole rotation subtract it by the minor arc (92 degrees) which will equal the major arc (B=268 degrees)
Are you sure this is the COMPLETE problem?
2/3 • 1/5 = 2/15
'of' always means multiplication.
