QUESTION 1:

Divide:
(i) 102 by 17
(ii) −85 by 5
(iii) −161 by −23
(iv) 76 by −19
(v) 17654 by −17654
(vi) (−729) by (−27)
(vii) 21590 by −10
(viii) 0 by −135


ANSWER 1:


QUESTION 2:

Fill in the blanks:
(i) 296 ÷ ... = −148
(ii) −88 ÷ ... = 11
(iii) 84 ÷ ... = 12
(iv) ....... ÷ −5 = 25
(v) ....... ÷ 156 = −2
(vi) ....... ÷ 567 = −1


ANSWER 2:


(iv) 25×(5) = 12525×(-5) = -125
∴ 125÷5 = 25-125÷-5 = 25
(v) 156×(2) = 312156×(-2) = -312
∴ 312÷156 = 2-312÷156 = -2
(vi) 567×(1) = 567567×(-1) = -567
∴ 567 ÷ 567 = 1 


QUESTION 3:

Which of the following statements are true?
(i) 0 ÷ 4 = 0
(ii) 0 ÷ (−7) = 0
(iii) −15 ÷ 0 = 0
(iv) 0 ÷ 0 = 0
(v) (−8) ÷ (−1) = −8
(vi) −8 ÷ (−2) = 4

ANSWER 3:

Because LHS is equal to RHS, the equation is true. 

Because LHS is equal to RHS, the equation is true. 


Because LHS is not equal to RHS, the equation is false. 


Because LHS is not equal to RHS, the equation is false.
