Odpowiedź:
(2 2/3 + 4 2/3) : 3 2/3 = 6 4/3 : 11/3 = 22/3 * 3/11 = 2
2 2/5 : (4 - 3 3/5) = 12/5 : 2/5 = 12/5 * 5/2 = 6
1/4 : 2 3/4 +5 : 2 1/2 = 1/4 : 11/4 =1/4 * 4/11 = 1/11
5 1/4 : (1/2)² - 2 2/7 : 1 3/5 = 21/4 : 1/4 - 15/7 : 8/5 = 21/4 * 4 - 15/7 * 5/8 = 21 - 75/56 = 21 - 1 19/56 = 19 37/56
5 * (2/7 : 5/74) - 2 1/3 = 5 * (2/7 * 74/5) = 5 * 148/35 = 148/7 = 21 1/7
6 2/9 * (5 - 4 1/2 : 9) = 56/9 * (5 - 9/2 * 1/9) = 56/9 * (5 - 1/2) = 56/9 * 4 1/2 =
= 56/9 * 9/2 = 28
