Answer 1

zad.2 Oblicz 

 

1 5/6 + 2 4/7=  11/6 + 18/7 = 77/42 + 108/42 =185/42 =4 17/42

 

(3 2/3)²=(11/3)²=121/9=13,(4)

 

4 6/7 - 2 1/5= 4 30/35  - 2 7/35 = 2 23/35

 

8 2/9-3 5/8= 74/9 - 29/8= 592/72 -261/72= 331/72= 4 103/72

7/15*3/4=7/20

4/7/8/21=4/7*1/8 /21= 1/14*1/21=1/94

2 2/3*1 3/4=8/3*7/4=14/3=4 2/3

6/13/3 3/5=6/13 /18/5=6/13*5/18=5/39

Umiem tylko to ale na 100% dobrze :D
