Answer 1

zad.1

4 2/3 : 3 1/2 = 14/3 : 7/2= 14/3 * 2/7 = 4/3

7 1/5 : 3 1/5= 36/5 : 16/5= 36/5*5/16= 9/4

5 5/6: 2/15 = 35/6:2/15= 35/6* 15/2= 75/2

zad. 2

a) 2/3:4/6=2/3*6/4= 2/2= 1

b) 14/25: 7/30= 14/25 * 30/7 = 12/5

c)4/7 : 15/21= 4/7*21/15= 4/5

d) 11/18 : 33/9= 11/18 * 9/33= 1/6

e) 24/13 : 1 5/13 = 24/13: 18/13 = 24/13* 13/18= 4/3

f) 1/15: 3 1/3 = 1/15: 10/3= 1/15* 3/10= 1/50

 

 

 

Answer 2

1. 

4 i 2/3 : 3 i1/2 = 14/3 : 7/2= 14/3 * 2/7 = 2/3*2/1 = 4/3 = 1i1/3

7 i1/5 : 3 i1/5 = 36/5 : 16/5 = 36/5 * 5/16 = 9/1 *1/4 = 9/4 = 2 i 1/4

5i5/6 : 2/15 = 35/6 * 15/2 = 525/12 = 43 i 9/12 = 43 i 3/4

 

2.

2/3 : 4/6 = 2/3 * 6/4 = 1/1 *2/2 = 1 * 1 = 1

b)14/25 : 7/30= 14/25 * 30/7 = 2/5 *6/1 = 12/5 = 2 i 2/5

c) 4/7 ; 15/21 = 4/7 * 21/15 = 4/1 * 3/15 = 12/15

d) 11/18 : 33/9 = 11/18 * 9/33 = 1/2 * 1/3 = 1/6

e) 24/13 : 1i5/13 = 24/13 :18/13 = 24/13 * 13/18 = 4/1 * 1/3 = 4/3 = 1 i1/3

f) 1/15 : 3 i1/3 = 1/15 : 10/3 = 1/15 * 3/10 = 1/5 * 1/10 = 1/50
