Решите уравнение а)x+9.7/10=28.2/15 г)6.3/11+b=11.93/121 д)9.5/36-х=2.4/9 е)к-5.17/60=7.9/20

1)x+9.7/10=28.2/15 
x+0.97=1.88
x=1.88-0.97
x=0.91

2)6.3/11+b=11.93/121 
x+63/110=1193/12100
x=1193/12100 - 63/110 =-5737/12100

3)9.5/36-х=2.4/9 
19/72-x=4/15
x=-1/360

4)к-5.17/60=7.9/20
k-517/6000=0.395
k=0.395+ 517/6000
k=2887/6000
