а) (14/3 + 11/2) * 6 = ((28 + 33)/6) * 6 = 28 + 33 = 61

б) (3(2/7) + 5/7) * 7 = ((23 + 5)/7) * 7 = 23 + 5 = 28

в) (8 - 1(1/9)) * 9 = ((72 - 10)/9) *9 = 72 - 10 = 62

г) (4 - 1(1/3) * 2) * 15 = (4 - 8/3) * 15 = ((12 - 8)/3) * 15 = 4/3 * 15 = 20

д) 8(5/11) * 4(2/9) + 8(5/11) * 6(7/9) = 8(5/11) * (4(2/9) + 6(7/9)) = 8(5/11) * (4(2/9) + 6(7/9)) = 8(5/11) * 11 = 93

e) 6(3/5) * 7(1/6) - 2(1/6) * 6(3/5) = 6(3/5) * (7(1/6) - 2(1/6)) = 6(3/5) * ((43 - 13)/6) = 6(3/5) * 30/6 = 33/5 * 30/6 = 33

ж) 9(3/8) * 2(5/7) - 2(5/7) * 7(3/8) = 2(5/7) * (9(3/8) - 7(3/8)) = 2(5/7) * (9(3/8) - 7(3/8)) = 2(5/7) * 2 = 38/7

з) 3(3/4) * 3(3/4) + 3(3/4) * 1/4 = 3(3/4) * (3(3/4) + 1/4) = 3(3/4) * (3(3/4) + 1/4) = 3(3/4) * 4 = 60/4 = 15
