Proszę o odpowiedzi ; ] Aha i znak / to jest kreska ułamkowa jakby co ; D

Answer 1

10-7 3/5 = 2²/₅

 

2 i 3/8 - 1 i 5/8 =19/8 -13/8=6/8=3/4

 

6/5 - 5/6 = 36/30 -25/30 =11/30

 

2 i 3/4 - 1 i 2/3 =  11/4 -5/3 =33/12 -20/12=13/12 =1 i 1/12

 

4 i 1/3 -1 i 5/6 =  13/3 - 11/6 =26/6 -11/6 =15/6 =2 i 3/6

 

1/3 * 3/5 * 5/8 = 1/8

4/5 * 2 i 6/7 * 1i 3/4 = 4/5 ·20/7 · 7/4 =4/1=4

 

4 * 3 i1/8 * 3/10 = 4· 25/8 ·3/10 =100/8 ·3/10 =30/8=3 i 6/8 =3 i 3/4

 

40 : 2/5 = 40 ·5/2 =100

 

16/25 : 8 =16/25 · 1/8 = 2/25

 

3 i 5/7 : 3i  1/4=  26/7 : 13/4 =26/7 · 4/13 =8/7 =1 i 1/7

 

1 i 1/2 : 2 i 1/4= 3/2 : 9/4 =3/2 · 4/9 =6/9=2/3
