1.
1 5/6 + 3 3/14 : (6 - 3 3/7) = 1 5/6 + 42/14 : 2 4/7 = 1 5/6 + 42/14 : 18/7 =
= 1 5/6 + 21/7 * 7/18 = 1 5/6 + 21/18 = 1 5/6 + 1 3/18 = 1 5/6 + 1 1/6 = 2 6/6 = 3
2.
9/16 * (1 1/3 - 1/4) * 16/3 = 9/16 * (1 4/12 - 3/12) * 16/3 = 9/16 * 1 1/12 * 16/3 =
= 9/16 * 13/12 * 16/3 = 3 * 13/12 = 13/4 = 3 1/4
