8 1/2 + 1 2/5 = 8,5 + 1,4 = 9,9
10 1/4 - 6 1/5 = 10 5/20 - 6 4/20 = 4 1/20
11 5/8 + 8 101/125 = 11 625/1000 + 8 808/1000 =20,433
21 15/16 - 19 3/125 =21 1875/2000 - 19 48/2000 = 2 1827/2000

8/15*(-1/2)-3/10:(-6/5)=1/20
1)8/15*(-1/2)=-4/15
2)-3/0:(-6/5)=-3/10*(-5/6)=1/4
3)-4/15+1/4=-12/60+15/60=3/60=1/20
