1. Express each of the following as a rational number with positive denominator:

(i) 15/(-28)

(ii) 6/(-9)

(iii) -28/(-11)

(iv) 19/(-7)

2. Express 3/5 as a rational number with numerator:

(i)  6

(ii) -15

(iii) 21

(iv) -27

3. Express (-3)/5 as a rational number with denominator.

(i) 20

(ii) -30

(iv) -84

5. Express 3/4 as a rational number with denominator:

(i) 20

(ii) 36

(iii) 44

(iv) -80

6. Express 2/5 as a rational number with numerator

(i) -56

(iv) -48

8. Express 168/(-294) as a rational number with denominator :

(i) 14

(ii) -7

(iii) -49

(iv) 1470

9. Write (-14)/42 in a form so that the numerator is equal to:

(i) -2

(ii) 7

(iii) 42

(iv) -70

10. Express (-42)/98 as a rational number with denominator 7.

11. Express (-48)/60 as a rational number with denominator 5.

12. Select those rational numbers which can be written as a rational number with numerator 6:
1/22, 2/3, 3/4, 4/(-5), 5/6, (-6)/7, (-7)/8

13. Select those rational numbers which can be written as a rational number with denominator 4:

7/8, 64/16, 36/(-12), (-16)/17, 5/(-4), 140/28

14. In each of the following, find an equivalent form of the rational number having a common denominator:

(i) 3/4 and 5/12

(ii) 2/3, 7/6 and 11/12

(iii) 5/7, 3/8, 9/14 and 20/21
