1st Picture:

`3)- (6)/(7) +\frac {10}{11} \\\\LCD:77 \\\\(6)/(7)* (11)/(11) + (10)/(11)*(7)/(7)= (66)/(77) + (70)/(77) = (136)/(77) = 1(59)/(77) \\ \\ 4) 3(6)/(7)* 2 (1)/(10)= (27)/(7) * (21)/(10) = (567)/(70) =(81)/(10) = 8(1)/(10) \\\\5)2(1)/(2)+3(1)/(3) \\\\LCD: 6 \\\\ 2(3)/(6) + 3(2)/(6) =5(5)/(6) \\\\6)5(1)/(8)*-6(6)/(11)=(41)/(8)* (72)/(11)=(2952)/(88)=(369)/(11)=33(6)/(11)`
