(4+5 1/6)*(3 2/3-13/33)

4=(4*6/6)=24/65 1/6=(30+1)/6=31/63 2/3=(9+2)/3=11/3=11*11/3*11=121/331)24/6+31/6=55/62)121/33-13/33=108/33=36/113)55/6*36/11=(5*11*6*6)/(6*11)=5*6=30Ответ: 30

(4 + 5 1/6) * (3 2/3 - 13/33) = 30,1) 4 + 5 1/6 = 24/6 + 31/6 = 55/6 = 9 1/6,2) 3 2/3 - 13/33 = 11/3 - 13/33 = 121/33 - 13/33 = 108/33 = 3 3/11,3) 9 1/6 * 3 3/11 = 55/6 * 108/33 = 30
