Answer 1

4.a) 6/12 = 1/2; 1/2 = 3/6
       14/21 = 2/3; 2/3 = 4/6
   b) 5/20 = 1/4; 1/4 = 5/20
       22/55 = 2/5; 2/5 = 8/20
   c) 9/27 = 1/3; 1/3 = 4/12
       9/36 = 1/4; 1/4 = 3/12
   d) 48/60 = 4/5; 4/5 = 28/35
       32/56 = 4/7; 4/7 = 20/35

5.a) 4/5 = 16/20
        7/10 = 14/20
        3/4 = 15/20
        14/20 < 15/20 < 16/20, adica 7/10 < 3/4 < 4/5
   b) 2/3 = 12/18
        4/9 = 8/18
        20/24 = 10/12 = 5/6 = 15/18
       8/18 < 12/18 < 15/18, adica 4/9 < 2/3 < 20/24
   c) 11/12 = 22/24
        6/16 = 3/8 = 9/24
       25/30 = 5/6 = 20/24
       9/24 < 20/24 < 22/24, adica 6/15 < 25/30 < 11/12
   d) 3 si 1/6 = 19/6 = 38/12
       1 si 2/3 = 5/3 = 20/12
       2 si 3/4 = 11/4 = 33/12
       20/12 < 33/12 < 38/12, adica 1 si 2/3 < 2 si 3/4 < 3 si 1/6

Answer 2

4 a)  6/12 = 1/2   si 14/21 = 2/3
cmmmc al numerelor ( 2, 3 ) = 2 x 3 = 6
1/2 = 3/6
2/3 = 4/6

b)  5/20 = 1/4  si    22/55 = 2/5
cmmmc al numerelor ( 4,5) = 20 
1/4 =5/20 
2/5 = 8/20

c) 9/27 = 1/3    si  9/36 = 1/4 
cmmmc al numerelor ( 3,4) = 12
1/3 = 4/12
1/4 = 3/12

d) 
48/60 = (48 : 6) / ( 60 : 6 ) = 8/10 = 4/5
32/56 =  ( 32: 8)/ ( 56 : 8 ) = 4/7
cmmmc al numerelor ( 5, 7) = 35
4/5 = 28/35
4/7 = 20/35

6) 
a) 4/5,  7/10 ,  3/4
cmmmc al numerelor ( 5, 10, 4 ) = 20

4/5 = 16/20 
7/10 = 14/20 
3/4 = 15/20
14/20 < 15/20 < 16/20
  ↓              ↓          ↓
 7/10  < 3/4 < 4/5

b)  2/3, 4/9,  20/24= 5/6
cmmmc al numerelor ( 3, 9, 6) = 2 ×3²= 18
2/3 = 12/18
4/9 = 8/18
5/6 = 15/18

8/18 < 12/18 < 15/18
   ↓          ↓            ↓
  4/9  <   2/3   <   5/6

c)  11/12;  6/16 = 3/8;  25/30 = 5/6
cmmmc al numerelor ( 12, 8, 6) = 2³×3=24

11/12= 22/24 
3/8 = 9/24 
5/6 = 20/24

9/24  <  20/24 < 22/24 
  ↓            ↓           ↓
  3/8   <  5/6   <   11/12


d)   
3 intregi si 1/6 = 19/6
1 intreg si 2/3 = ( 1 x 3 +2)/3 = 5/3
2 intregi si 3/4 = 11/4
cmmmc ( 6, 3, 4 ) = 12
19 /6  = 38 /12
5/3 = 20/12
11/4 = 33/12

20/12  < 33/12  <   38/12
   ↓               ↓            ↓
   5/3    <  11/4    <  19/6
