Answer 2

6 1/2 = (6x2+1)/2 = 13/2

3 2/3 = (3x3+2)/3 = 11/3

4 1/6 = (4x6+1)/6 = 25/6

a = 13/2 + 11/3 - 25/6 amp. 13/2 cu 3 si pe 11/3 cu 2

a = 39/6 + 22/6 - 25/6

a = 36/6

a = 6

b = 71/6 - 101/12 - 1 amp. 71/6 cu 2 si pe 1 cu 12

b = 142/12 - 101/12 - 12/12

b = 29/12

E = 2/3 + 6 - 29/12

E = 8/12 + 72/12 - 29/12

E = 51/12 = 17/4
