Answer 1

1)

3 intregi si 1 / 2 = ( 3 x 2 + 1 ) / 2 = 7 / 2

3 intregi si 2 / 3 = ( 3 x 3 + 2 ) / 3 = 11 / 3

7 intregi si 1 / 4 = ( 7 x 4 + 1 ) / 4 = 29 / 4

6 intregi si 1 / 2 = ( 6 x 2 + 1 ) / 2 = 13 / 2

5 intregi si 2 / 7 = ( 5 x 7 + 2 ) / 7 = 37 / 7

5 intregi si 2 / 5 = ( 5 x 5 + 2 ) / 5 = 27 / 5

3 intregi si 1 / 6 = ( 3 x 6 + 1 ) / 6 = 19 / 6

2)

0,( 25 ) = 25 / 99

5,(6) = ( 56 - 5 ) / 9 = 51 / 9 = 17 / 3

2,7 = 27 / 10

11,2 = 112 / 10 = 56 / 5

3,25 = 325 / 100 = 65 / 20 = 13 / 4

0,5 = 5 / 10 = 1 / 2

1, 1( 3) = ( 113 - 11 ) / 90 = 102 / 90 = 34 / 30 = 17 / 15

9,31 = 931 / 100

0,0(3) = 3 / 90 = 1 / 30

Answer 2

1)

3 si 1 / 2 = ( 3 × 2 + 1 ) / 2 = 7 / 2

3 si 2 / 3 = ( 3 × 3 + 2 ) / 3 = 11 / 3

7 si 1 / 4 = ( 7 × 4 + 1 ) / 4 = 29 / 4

6 si 1 / 2 = ( 6 × 2 + 1 ) / 2 = 13 / 2

5 si 2 / 7 = ( 5 × 7 + 2 ) / 7 = 37 / 7

5 si 2 / 5 = ( 5 × 5 + 2 ) / 5 = 27 / 5

3 si 1 / 6 = ( 3 × 6 + 1 ) / 6 = 19 / 6

2)

0,( 25 ) = 25 / 99

5,(6) = ( 56 - 5 ) / 9 = 51 / 9 = 17 / 3

2,7 = 27 / 10

11,2 = 112 / 10 = 56 / 5

3,25 = 325 / 100 = 65 / 20 = 13 / 4

0,5 = 5 / 10 = 1 / 2

1, 1( 3) = ( 113 - 11 ) / 90 = 102 / 90 = 34 / 30 = 17 / 15

9,31 = 931 / 100

0,0(3) = 3 / 90 = 1 / 30

3)

17 / 10 = 1 si 7/10 sau 1,7

12 / 5 = 2 si 2/5 sau 2,4

3 / 9 = 1/3 = 0,33333=0,(3)

10 / 8 = 1 si 2/8 sau 1,25
