1) 1. 5/7 - 2. 11/14 = 1. 10/14 - 2. 11/14 = -1. 1/14
2) 2. 8/21 : (-1. 1/14) = 50/21 : (-15/14) = 50/21 * (-14/15) = 10/3 * (-2/3) = -20/9
3) -20/9 * 4. 1/2 = -20/9 * 9/2 = -20/2 = -10
4) -10 - 1. 2/21 = -11. 2/21
5) 1. 11/25 * (-11. 2/21) =
36/25 * (-233/21) = -8388/525
6) -8388/525 : 2. 2/3 =
-8388/525 : 8/3 = -8388/525 * 3/8 = -25164/4200 = -5. 4164/4200 = -5. 347/350
