Пошаговое объяснение:
№ 4
4 1/3 * 3/4 13/3 * 3/4 13/4
---------------- = -------------- = -------- = 13/4 : 13/16 = 13/4 * 16/13 = 4
13/16 13/16 13/16
№ 5
15/32 : (3 4/7 * 2 5/8) = 15/32 : (25/7 * 21/8) = 15/32 : 75/8 = 15/32 * 8/75 = 1/20
№ 6
(7/9 + 0,7 - 5/6) : 3 13/15 = (7/9 + 7/10 - 5/6) : 3 13/15 = (210/270 + 189/270 - 225/270) : 3 13/15 = 174/270 : 3 13/15 = 29/45 : 58/15 = 29/45 * 15/58 = 1/3 * 1/2 = 1/6
