А) = (7/3 - 27/8) 8* 24/5 + 22/9 = - 25/8 * 24/5 = -5/3 + 22/9 = 7/9
Б) = 23/5 : (5/3 - 16/5) + 11/8 = 23/5 : (-23/15) + 11/8 = - 3/3 + 11/8 = 9/24 = 3/8
В) = 19/12 + 41/7 : (12/5 - 25/7) = 19/12 + 41/7 : (-41/35) = 19/12 - 5/5 = 35/60 = 7/12
Г) = 19/11 + 40/19 * (9/5 - 11/4) = 19/11 + 40/19 * (-19/20) = 19/11 - 2/2 = 16/22 = 8/11
Д) = 16/11 - 48/23 * (8/5 - 11/4) = 16/11 - 48/23 * (-23/20) = 16/11 + 12/5 = 212/55 = 3 47/55
Е) = 29/5 : (11/7 - 12/5) + 8/5 = 29/5 : (-29/35) + 8/5 = -7/7 + 8/5 = 91/35 = 13/5 = 2 3/5
Дополнительные множетели, думаю сообразишь где и какие дописать.
