1. 34/3 : 88/21 : 17/4 = 34/3 * 21/88 * 4/17 = 1/11
2. (18/5 - 11/5) * 5 = 7/5 * 5 = 7
3. 1cała i 8/15 * 1cała i 7/23 = 23/15 * 30/23 = 2

liczę na naj ;)
1. 11 i 1/3 : 4/21 : 4 i 1/4 = 34/3 x 21/4 x 4/17 = 14/1 = 14
2. (3 i 3/5 - 2 i 1/15) x 5= (18/5 - 31/15) x 5 = (54/15 - 31/15) x 5 = 23/15 x 5 = 23/3 = 7 i 2/3
3. (4 - 2 i 7/15) x (10 - 8 i 16/23) = (4/1 - 37/15) x (10/1 - 200/23) = (60/15 - 37/15) x (230/23 - 200/23) = 23/15 x 30/23 = 2/1 = 2
4. 12/3 x 6/7 : 4/7 = 12/3 x 6/7 x 7/4 = 6/1 = 6
5. (7 i 7/8 - 3 i 3/8) : 4 i 1/2 = 4 i 1/2 : 4 i 1/2 = 9/2 x 2/9 = 1/1 = 1
Mam nadzieję, że pomogłam. :)
