a) 1 5/6 : 3 2/3 * 1 1/7 = 11/6 : 11/3 * 8/7 = 11/6 * 3/11 * 8/7 = 1/2 * 1/1 * 8/7 = 1/2 * 8/7 = 1/1 * 4/7 = 4/7
b) (1/2)³ * 2 2/3 : 1 1/6 = 1/8 * 8/3 : 7/6 = 1/1 * 1/3 : 7/6 = 1/3 * 6/7 = 1/1 * 2/7 = 2/7
c) 1 1/4 * 6 - 3 : 1 1/5 = 5/4 * 6/1 - 3/1 : 6/5 = 5/2 * 3/1 - 3/1 * 5/6 = 15/2 - 1/1 * 5/2 = 15/2 - 5/2 = 10/2 = 5
