Question 1. Which of the following are positive rational numbers?

Answer:

Question 2. Which of the following are negative rational numbers?

Answer:

Question 3. Find four rational numbers equivalent to each of the following rational numbers:

(i) 3/−7
(ii) −5/−9

Answer:

Question 4. Write each of the following rational numbers with positive denominators:

(i) 4/−9
(ii) 17/−33
(iii) −15/−38

Answer:

Question 5. Express 5/-9 as a rational number with

(i) numerator = 20

(ii) numerator = -35

(iii) denominator = -54

(iv) denominator = 72

Answer:

(i) numerator = 20

= 5/-9 = (5 x 4)/(-9 x 4)

= 20/-36

(ii) numerator = -35

= 5/-9 = (5 x -7)/(-9 x -7)

= -35/63

(iii) denominator = -54

= 5/-9 = (5 x 6)/(-9 x 6)

= 30/-54

(iv) denominator = 72

= 5/-9 = (5 x -8)/(-9 x -8)

= -40/72

Question 6. Express -80/112 as a rational number with

(i) numerator = -5

(ii) denominator = -14

Answer:

(i) numerator = -5

= -80/112 = (-80 ÷ 16)/(112 ÷ 16)

= -5/7

(ii) denominator = -14

= -80/112 = (-80 ÷ 16)/(112 ÷ 16)

= -5/7 = (-5 x 2)/(7 x 2)

= -10/14
