=4/5
=5 i 5/7
zad. 2
=14/3
=15/4
=38/5
=39/3
zad.4
=1 i 5/15 +9/15=1 i 14/15
=2 i 20/24+ 1 i 9/24=3 i 29/24= 4 i 5/24
=10/18 + 15/18 = 25/18 = 1 i 7/18
=6 i 6/8 - 7/8 =5 i 14/8 - 7/8 =5 i 7/8
=6 i 7/9 - 6/9 =6 i 1/9
=1 i 7/14 - 12/14 = 21/14 -12/14 =9/14
= 7 i 15/20 -5 i 16/20 =6 i 35/20 - 5 i 16/20 =1 i 19/20
zad.5
= 5/3 *9/10 = 27/30 =skracam przez 3 =9/10
=83/16 * 8 = 83/16 * 8/1 = 8 z 16 skrócą sie i =83/2 = 41 i 1/2
= 3/4 * 3/4 * 3/4 =27/64
=12 * 15/4 = 12/1 * 15/4 = 12 i 4 skracam przez 4 i =3/1 *15/1 =45
=10/3 * 12/5 =( 10 skróci się z 5 przez 5 a 12 z 3 przez 3) =2* 4 = 8
= 8/7 * 8/7 =64/49 = 1 i 15/49
= 5/6 * 1/3= 5/18
=6 * 4/7== 24/7 = 3 i 3/7
=36/5 * 1/8=( 36 i 8 skracam przez 4 ) =9/5 *1/2 = 9/10
=2/3 *4/3 =8/9
=26/7 *3/2 =( 26 i 2 skracam przez 2) =13/7 *3/1 =39/7 =5 i 4/7
=4/3 *5/12 = ( 4 i 12 skracam przez 4)= 1/3 * 5/3 =5/9

Answer 2

1.
3/5 = 9/15     1 i 4/7 = 1 i 20/35       25/45 = 5/9    4 i 24/36 = 4 i 2/3
2/9 = 8/36     2 i 5/12 = 2 i 25/60     32/40 = 4/5    5 i 30/42 = 5 i 5/7

2.
4 i 2/3 = 14/3     3 i 3/4 = 15/4   7 i 3/5 = 38/5    13 = 39/3

4.
1 i 1/3 + 3/5 = 1 i 5/15 + 9/15 = 1 i 14/15
2 i 5/6 + 1 i 3/8 = 2 i 20/24 + 1 i 9/24 = 3 i 29/24 = 4 i 5/24
5/9 + 5/6 = 20/36 + 30/36 = 50/36 = 1 i 14/36 = 1 i 7/18
6 i 3/4 -- 7/8 = 6 i 6/8 - 7/8 = 5 i 14/8 - 7/8 = 5 i 7/8
6 i 7/9 -- 2/3 = 6 i 7/9 - 6/9 = 6 i 1/9
1 i 1/2 -- 6/7 = 1 i 7/14 - 12/14 = 21/14 - 12/14 = 9/14
7 i 3/4 -- 5 i 4/5 = 7 i 15/20 - 5 i 16/20 = 6 i 35/20 - 5 i 16/20 = 1 i 19/20

5.
1 i 2/3 * 9/10 = 5/3 * 9/10 = 45/30 = 1 i 15/30 = 1 i 1/2
5 i 3/16 * 8 = 83/16 * 8/1 = 664/16 = 41 i 5/16
(3/4) do potęgi 3 = 3/4 * 3/4 * 3/4 = 9/16 * 3/4 = 27/64
12 * 3 i 3/4 = 12/1 * 15/4 = 180/4 = 45
3 i 1/3 * 2 i 2/5 = 10/3 * 12/5 = 120/15 = 8
(1 i 1/7) do potęgi 2 = (8/7) do potęgi 2 = 8/7 * 8/7 = 64/49 = 1 i 15/49

5/6 : 3 = 5/6 : 3/1 = 5/6 * 1/3 = 5/18
6 : 1 i 3/4 = 6/1 : 7/4 = 6/1 * 4/7 = 24/7 = 3 i 3/7
7 i 1/5 : 8 = 36/5 : 8/1 = 36/5 * 1/8 = 36/40 = 9/10
2/3 : 3/4 = 2/3 * 4/3 = 8/9
3 i 5/7 : 2/3 = 26/7 * 3/2 = 78/14 = 5 i 8/14 = 5 i 4/7
1 i 1/3 : 2 i 2/5 = 4/3 : 12/5 = 4/3 * 5/12 = 20/36 = 5/9

Proszę :) Masz jeszcze rozpisane działania, żeby nie było.
