3/4*1. 1/3 - 5/6*3/5 - 2/3 =
3/4*4/3 - 3/6 - 2/3 =
1 - 3/6 - 4/6 =
3/6 - 4/6 = -1/6
ответ: -1/6
1/8(6a-4)-1/12(10b+2)= 6/8а - 4/8 - 10/12b - 2/12 = 3/4a - 1/2 - 5/6b - 1/6 =
3/4a - 3/6 - 5/6b - 1/6 = 3/4a - 5/6b - 2/3 =3/4*1 1/3 - 5/6*3/5 - 2/3 = 3/4*4/3-3/6 - 2/3 = 1 - 3/6 - 4/6 = 3/6 - 4/6 = -1/6
ответ:-1/6
