Пошаговое объяснение:
1) 24/(7+13)=24/20=6/5=1.2;
2) (45-28)/34=17/34=1/2=0.5;
3) 102/(100-15)=102/85=6/5=1.2;
4) (60-45)/(3*13+6)=15/(39+6)=15/45=1/3;
5) (8*4-8*3)/12=8(4-3)/12=8/12=2/3;
6) (15*5-15*3)/60=15(5-3)/60=15*2/60=1/2=0.5;
7) (9*7-2*9)/(65+25)=9(7-2)/90=9*5/90=45/90=1/2=0.5;
8) (12*8-2*8)/(21+43)=8(12-2)/64=8*10/64=10/8=5/4=1.25.
