А) (5/6 - 2/3) : 8/9 = 3/16
1) 5/6 - 2/3 = 5/6 - 4/6 = 1/6
2) 1/6 : 8/9 = 1/6 * 9/8 = 3/16

б) 3/10 : (2/5 + 3/15) = 1/2
1) 2/5 + 3/15 = 6/15 + 3/15 = 9/15 = 3/5
2) 3/10 : 3/5 = 3/10 * 5/3 = 1/2

в) 10 : 2/5 - 3/10 = 24 7/10
1) 10 : 2/5 = 10 * 5/2 = 50/2 = 25
2) 25 - 3/10 = 24 10/10 - 3/10 = 24 7/10

г) (1 1/2 - 3/8) : 3 = 3/8
1) 1 1/2 - 3/8 = 1 4/8 - 3/8 = 1 1/8
2) 1 1/8 : 3 = 9/8 * 1/3 = 3/8
