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
