Answer 2

Odpowiedź:

3/4 * 4 = 12/4 = 3

2/7 * 7 = 14/7 = 2

10 * 1/5 = 10/5 = 2

1/8 * 3 = 3/8

2 * 3/5 = 6/5 = 1 i 1/5

6/7 : 2 = 6/7 * 1/2 = 6/14 = 3/7

8/9 : 4 = 8/9 * 1/4 = 2/9

6/5 : 3 = 6/5 * 1/3 = 2/5

6 : 5 = 6/5 = 1 i 1/5

3 : 9 = 3/9 = 1/3

zad 2

4/9 * 3/4 = 1/3

5/8 : 7/12 = 5/8 * 12/7 = 15/14 = 1 i 1/14

7/8 * 24/33 = 21/33

1 i 1/8 * 4/15 = 9/8 * 4/15 = 3/10

2 i 3/5 : 5 = 13/5 * 1/5 = 13/25

1 i 5/7 : 6 = 12/7 * 1/6 = 2/7

6 i 1/2 : 3 i 1/4 = 13/2 * 4/13 = 2

7 i 1/3 ; 2 i 2/5 = 22/3 * 5/12 = 55/18 = 3 i 1/18

2 * (13 *4)/8 = 2 * 52/8 = 52/4 = 13

8 i 3/4 * 4/7 * 3 = 35/4 * 4/7 * 3 = 5 * 3 = 15

2 i 1/7 * 7 * 2 i 2/5 = 15/7 * 7 * 12/5 = 15 * 12/5 = 36

4 * (15 * 9)/12 = 4 * 135/12 = 135/3 = 45
