(8 8/8 -5 3/8)(4 5/12 -4*3/8 +(3/10 -1/2 *1/4) *4/7)/(1/24 +1/4 *3/40)=3 5/8 *(4 5/12 -3/2 +(3/10 -1/8) *4/7)/(1/4 *(1/6 +3/40))=29/8 *(3 17/12 -1 6/12 +(12/40 -5/40) *4/7)/(1/4 *(20/120 +9/120))=29/2 *(2 11/12 +7/40 *4/7)/(29/120)=29/2 *(2 11/12 +1/10) *120/29=(2 55/60 +6/60)*60=2 61/60 *60=181/60 *60=181

(((3 14/35 +1 25/35) *35/3)/(1 4/18 -1 1/18) -((9 21/12 -1 10/12) *6)/((4 23/20 -4 5/20) *10/9)) *2/45=((179/35 *35/3)/(1/6) -(107/12 *6)/(9/10 *10/9)) *2/45=(179/3 *6 -107/2)*2/45=(179-107)*2/45=154/45=3 19/45

((161/252 +124/252)-(63/84 +20/84))*48:(3/5 *8/7)/((57/78 +28/78 -13/78)*325/6 :(60/7 *35/12))=((95/84 -83/84)*48 *35/24)/(12/13 *325/6)=(1/7 *70)/(650/13)=10*13/650=13/65

3 1/4 -((6*5/3 -7/6 *6/7)/(21/5 *10/11 +5 2/11) -((3/20 +10/20 -1/15) *12/49)/(3 3/9 +2/9)) *7/3=3 1/4 -((10-1)/(3 9/11 +5 2/11) -((39/60 -4/60) *12/49)/(32/9)) *7/3=3 1/4 -(9/9 -7/12 *12/49 *9/32) *7/3=3 1/4 -(1 -1/7 *9/32) *7/3=3 1/4 -(1 -9/224) *7/3=3 1/4 -(224/224 -9/224) *7/3=3 1/4 -215/224 *7/3=3 1/4 -215/96=3 24/96 -2 23/96=1 1/96
