Question

uzupelnij liczniki i mianowniki ulamkow.

?/2 = ?/8 =?/6 = 6/12 = ?/12 = ?\24 = ?/48 = ?/60

18/? = 12/? = 6/? = 3/? = 2/? = 1/3 = ?/18 = ?/30 = ?/36 =?/24

rozluz na czynniki pierwsze liczbe 30. napisz kilka ulamkow niewlasciwych, ktorych mianowniki sa czynikami pierwszymi liczby 30 (po 3 ulamki o danym mianowniku). ulamki nie wlasciwe zapisz w postaci liczby mieszanej.

uporzadkuj ulamki malejaco: 2 1/4, 7/4, 1 5/8, 2/3, 3/2, 3/9, 1 3/5, 8/7

Answer 1

1/2 = 4/8 =3/6 = 6/12 = 12\24 = 24/48 = 30/60

18/54 = 12/36 = 6/18 = 3/9 = 2/6 = 1/3 = 6/18 = 10/30 = 12/36 =8/24

 

 

30=3*5*2
9/2=4 1/2

5/2=2 1/2

 

7/2=3 1/2
12/5=2 2/5

8/5=1 3/5

 

19/5=3 4/5
5/3=1 2/3

10/3=3 1/3

13/3= 4 1/3

 

2 1/4 = 2,25

7/4 = 1,75

1 5/8 = 1,625

2/3 = 0,(66)

3/2 = 1,50

3/9 = 0,(33)

1 3/5 = 1,60

8/7 = 1,14

 

3/9<2/3 <8/7<3/2<1 3/5<1 5/8<7/4<2 1/4

 

 

 

 

 

Answer 2

1/2=4/8=3/6=6/12=6/12-12/24=24/48=30/60

18/54=12/36=6/18=3/9=2/6=1/3=6/18=10/30=12/36=8/24

30=2*3*5

5/2=2 1/2, 7/2=3 1/2, 9/2=4 1/2

4/3=1 1/3, 5/3=1 2/3, 7/3=2 1/3

6/5=1 1/5, 7/5=1 2/5, 11/5=1 1/5

 

9/4, 7/4, 13/8, 2/3, 3/2, 3/9, 8/5, 8/7

9/4=5670/2520

7/4=4410/2520

13/8=4095/2520

2/3=1680/2520

3/2=3780/2520

3/9=840/2520

8/5=4032/2520

8/7=2880/2520

9/4, 7/4, 13/8, 8/5, 3/2, 8/7, 2/3, 3/9

2 1/4, 7/4, 1 5/8, 1 3/5, 3/2, 8/7, 2/3, 3/9
