х= 2 7/12+5 3/18

х= 2 21/36+5 6/36

х=7 27/36

х=7 3/4

x - 37 17/54 = 15 16/45

х = 15 16/45 + 37 17/54

х= 52 181/270

х - 26 7/21 = 100 - 5/28

x = 99 23/28 + 26 1/3

x = 99 69/84 + 26 28/84

x = 126 13/84

X-33 21/25=42 17/35

Х=42 17/35+33 21/25

Х=75 85/175+147/175

Х=75 232/175

Х=76 57/175
