Pomocy matma nie kumam tego dajcie odp pls na dzisiaj

Answer 1

Odpowiedź:

b) 3 i 1/2 + 1/4= 3 i 2/4 + 1/4= 3 i 3/4

     2 i 3/4 - 1/2= 2 i 3/4- 2/4= 2 i 1/4

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

   2 i 1/4 + 7 i 1/2= 2 i 1/4 + 7 i 2/4=  9 i 3/4

zad.2

   1/4 + 5/8 = 2/8 + 5/8= 7/8

    5/6- 2/3= 5/6- 4/6= 1/6

zad.3

 a)  3/5 + 1/10= 6/10 + 1/10= 7/10

b)     2/3 + 1/6= 4/6+ 1/6= 5/6

c)   1 i 5/6 + 4 i 1/12= 1 i 10/12 + 4 i 1/12= 5 i 11/12

d)  4/5- 3/10= 8/10- 3/10= 5/10= 1/2

e)   8/3- 8/9= 24/9- 8/9= 16/9

f)  2 i 1/2 - 1/4= 2 i 2/4-1/4= 2 i 1/4

Answer 2

Odpowiedź:

zad 1

3 i 1/2 + 1/4 = 3 i 2/4 + 1/4 = 3 i 3/4

2 i 3/4 - 1/2 = 3 i 3/4 - 2/4 = 3 i 1/4

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

2 i 1/4 + 7 i 1/2 = 2 i 1/4 + 7 i 2/4 = 9 i 3/4

zad 2

1/4 + 5/8 = 2/8 + 5/8 = 7/8

5/6 - 2/3 = 5/6 - 4/6 = 1/6

zad 3

3/5 + 1/10 = 6/10 + 1/10 = 7/10

2/3 + 1/6 = 4/6 + 1/6 = 5/6

1 i 5/6 + 4 i 1/12 = 1 i 10/12 + 4 i 1/12 = 5 i 11/12

4/5 - 3/10 = 8/10 - 3/10 = 5/10 = 1/2

8/3 - 8/9 = 24/9 - 8/9 = 16/9 = 1 i 7/9

2 i 1/2 - 1/4 = 2 i 2/4 - 1/4 = 2 i 1/4
