A) 40º = π.(40/180) = π.(4/18) = π.(2/9) = 2π/9 

b) 36º = π.(36/180) = π.(1/5) = π/5 

 c) 25º = π.(25/180) = π.(5/36) = 5π/36 

d) 15º = π.(15/180) = π.(15/18) :(3/3) = π.(5/6) = 5π/6

e) 24º = π.(24/360) = π.(1/15) = π/15 

 f) 80º = π.(80/180)= π.(8/18) = π.(4/9) = 4π/9 

g) 192º = π.(192/180) = π.(91/90) = 91π/90 

h) 22º30'=> 22,5º = π.(22,5/180) .(2/2) = π.(45/360) :(45/45) = π.(1/8) = /8
