Question

oblicz:

6 : 2/3=

8:2 2/3=

5/6:10=

2 1/3: 7/8=

1/4 : 5/6=

3/4 : 6/7=

3/8:9/10=

1 1/8: 1 4/5=

daje 12 punktów

Answer 1

6 : 2/3 = 6/1 * 3/2 = 3/1 * 3/1 = 9/1 = 9

8 : 2 i 2/3 = 8 : 8/3 = 8 * 3/8 = 3

5/6 : 10 = 5/6 * 1/10 = 1/12 

2 1/3 : 7/8 = 7/3 * 8/7 = 2 2/3

1/4 : 5/6 = 1/2  * 3/5 = 3/10

3/4 : 6/7 = 3/4 * 7/6 = 7/8

3/8 : 9/10 = 3/8 * 10/9 = 5/12

1 1/8 : 1 4/5 = 9/8 : 9/5 = 5/8

Answer 2

 6 : 2/3 = 6 * 3/2 = 9 

 

8 : 2 i 2/3 = 8 : 8/3 = 8 * 3/8 = 3 ( chyba o to chodzilo pisz dokładnie ) 

 

5/6 : 10 = 5/6 * 1/10 = 1/12 

 

2 i 1/3 : 7/8 = 7/3 * 8/7 = 8/3 = 2 i 2/3 

 

1/4 : 5/6 = 1/4 * 6/5 = 3/10 

 

3/4 : 6/7 = 3/4 * 7/6 = 7/8 

 

3/8 : 9/10 = 3/8 * 10/9 = 5/12 

 

1 i 1/8 :1 i 4/5 = 9/8 : 9/5  = 9/8 * 5/9 = 5/8
