1/2:2/3

2/3:5/16

2/9:4/27

5/8:5/12

2 1/2*2 2/5

Answer 1

8 1\3 + 1 3\4 = 8 4\12 + 1 9\12 = 10 1\12

1 4\25 + 3 11\25 = 4 15\25

2 5\10 + 2 2\10 = 4 7\10

3 91\100 + 10 45\100 = 14 36\100

 

 

dalej nie wiem

Answer 2

8i1/3 + 1,75= 8i1/3 + 1i3/4= 8i4/12 +1i9/12= 9i13/12= 10i1/12

 

1,16 + 3i11/25= 1,16 + 3,44= 4,6      (3i11/25= 3,44)

 

2i1/2 + 2,2 = 2,5 + 2,2 = 4,7                (2i1/2 = 2,5)

 

3,91 + 10i9/20= 3,91 + 10,45 = 14,36         (10i9/20 = 10,45)

 

2i1/2 ; 1i2/3 = 5/2 : 5/3= 5/2 * 3/5= 1/2 * 3/1= 3/2= 1i1/2

 

3i3/4 : 2 i1/12= 15/4 : 25/12= 15/4 * 12/25 = 3/1 *3/5= 9/5= 1i4/5

 

1i1/3 : 1i7/9= 4/3 : 16/9= 4/3 * 9/16= 1/1 *3/4= 3/4

 

5i5/6 : 3i2/21= 35/6 : 65/21 = 35/6 * 21/65 = 7/2 * 7/13= 49/26= 1i23/26

 

5i3/5 : 5 = 28/5 : 5/1 = 28/5 *1/5= 28/25= 1i3/25

 

6 : 2i2/9= 6: 20/9 = 6 * 9/20= 54/20= 2i14/20= 2i7/10

 

2i2/3 : 4 = 8/3 : 4/1= 8/3 * 1/4= 2/3 *1/1 = 2/3 

 

8 : 4i4/5 = 8 : 24/5= 8* 5/24= 1* 5/3= 5/3= 1i2/3

 

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

 

2/3 : 5/16= 2/3 * 16/5 = 32/15= 2i2/15

 

2/9 :4/27= 2/9 * 27/4 = 1/1* 3/2= 3/2 = 1i1/2

 

5/8 : 5/12 = 5/8 * 12/5= 1/2 * 3/1= 3/2= 1i1/2

 

2i1/2 * 2i2/5= 5/2 * 12/5 = 1/1 * 6/1 = 6
