Odpowiedź:
1 3/5 * (- 15/2) - (2,7 * 2/9) 8/5 * (- 15/2) - (27/10 * 2/9)
------------------------------------- = ---------------------------------------- =
3,5 : 3 10/20 + (- 7,2) 35/10 : 70/20 + (- 72/10)
4/1 * (-3/1) - 3/5 * 1/1 - 12 - 3/5 - 12 3/5 - 63/5
------------------------------- = ----------------------- = ------------------- = -------------- =
35/10 * 20/70 - 72/10 1/1 * 2/2 - 72/10 1 * 1 - 72/10 -72/10
= (- 63/5) : (- 72/10) = (- 63/5) * (- 10/72) = (-63/1) * (-2/72) =
= 126/72 = 1 54/72 = 1 6/8 = 1 3/4
