Answer 1

1.

6 * 2/5 = 12/5 = 2 i 2/5

8 * 3/4 = 2 8 3 = 6

4/7 *14 = 4 8 2 = 8

7/12 * 9 = 7/4 *3 = 21/4 = 5 i 1/4

 

2.

4/5 * 2/3 = 8/15

5/8 * 4/8 = 5/2 * 1/8 = 5/16

3/5 * 10/21 = 2/7

2/3 * 3/4 * 5/8 = 1/2 * 5/8 = 5/16

Answer 2

Zadanie 1

6/1 * 2/5 = 12/5= 2 2/5

8/1 * 3/4 = 28/4= 6

4/7 * 14/1= 56/7= 8

7/12 * 9/1= 63/12= 5 3/12=5 1/4

Zadanie 2

4/5* 2/3 = 8/15

5/8 * 4/8 = 20/64=5/16

3/5 * 10/21 = 30/ 105=  2/7

2/3 * 3/4 * 5/8 = 30/96 = 5/16
