Question

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

Answer 1

4=(4*6/6)=24/6
5 1/6=(30+1)/6=31/6
3 2/3=(9+2)/3=11/3=11*11/3*11=121/33

1)24/6+31/6=55/6
2)121/33-13/33=108/33=36/11
3)55/6*36/11=(5*11*6*6)/(6*11)=5*6=30
Ответ: 30

Answer 2

(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
