Answer 1

6 i 1/4 * 1 i 3/4 + 1 = 25/4 * 7/4 + 1 = 175/16 + 1 = 10 i 15/16 + 1 = 11 i 15/16

 

1 i 1/7 * 7/8 * 21= 8/7* 7/8 * 21 = 1* 21= 21

 

9 : 1/8= 9 * 8 = 72

 

1/12 : 1/144 = 1/12 * 144 = 12

 

17: 1/3= 17*3 = 51

 

 

 

Answer 2

Zad.1)  6 1/4 * 1 3/4 + 1 = 25/4 * 7/4 + 1 = 175/16 + 1 = 10 15/16 + 1 = 11 15/16

Zad.2) 1 1/7 * 7/8 * 21 = 8/7 * 7/8 = 1*21= 21

Zad.3) 9: 1/8 = 9/1 * 8/1 = 72

Zad.4) 1/12 : 1/144 = 1/12 * 144/1 = 12

Zad.5) 17 : 1/3 = 17 * 3/1 = 51
