Answer 1

2/21

2/21

2/212/21

2/21

2/21

Answer 2

multiply both sides by 2/2

1/7 × 2/2 = 2/14

2/7×2/2 = 4/14

3/14 is the only number in between but then its not given in the following options.

now multiply both sides by 3/3

1/7×3/3 = 3/21

2/7 × 3/3 = 6/21

numbers in between 3/21 and 6/21 = 4/21,5/21

(d) 5/21 is the answer .
