Answer 2

zadanie 6

2 x 11/18 x 6= 11/9 *6 = 22/3 = 7 i 1/3

3 x 12/99 x 11 = 12/33 *11 = 12/3 = 4

12 x 11/18 x 2 = 22/3 *2 = 44/3 = 14 i 2/3

 

zadanie 7

100x 7/1000 = 7/10

4i1/5x15 = 21/5 *15 = 63

12x2 i7/15 = 12*37/15 = 148/5 = 29 i 3/5

9 x8i 8/9 = 9*80/9 = 80

1 i5/9 x 3 = 14/9 *3 = 14/3 = 4 i 2/3

Answer 3

zadanie 6

2 x 11/18 x 6= 22/108 = 11/54

3 x 12/99 x 11 = 2/33

12 x 11/18 x 2 = 33/3 = 11

 

zadanie 7

100x 7/1000 = 7/10 = 0,7

4i1/5x15 = 3/50

12x2 i7/15 = 12*2+7/15= 24+7/15

9 x8i 8/9 = 72+8/9

1 i5/9 x 3 = 1 5/9/3= 14/27
