2) (2 1/2 − 12/15) · 1/34 = (5/2 − 4/5) · 1/34 = 17/10 · 1/34 = 1/20.
4) (8/16 − 3 3/18) · 12 = (1/2 − 19/6) · 12 = −8/3 · 12 = −32.
6) 1 8/16 : (4 13/14 + 3/7) = 3/2 : (4 13/14 + 6/14) = 3/2 : 5 5/14 = 3/2 · 14/75 = 7/25.
8) 2 11/36 : (1 3/27 + 3 10/20) = 83/36 : (10/9 + 7/2) = 83/36 : 83/18 = 1/2.
10) 18 1/5 : (2 12/30 − 2 5/6) = 91/5 : (2 2/5 − 2 5/6) = 91/5 : (−13/30) = −42.
