Question

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

(i) 102 ÷ 17 = $\frac{\left|102\right|}{\left|17\right|}=\frac{102}{17}=$6
(ii) −85 ÷ 5 = $-\frac{\left|-85\right|}{\left|5\right|}=-\frac{85}{5}=$ − 17
(iii) −161 ÷ ( − 23) = $\frac{\left|-161\right|}{\left|-23\right|}=\frac{161}{23}=$ 7
(iv) 76 ÷ − 19 = $-\frac{\left|76\right|}{\left|-19\right|}=-\frac{76}{19}=$− 4
(v) 17654 ÷ (− 17654) = $-\frac{\left|17654\right|}{\left|-17654\right|}=-\frac{17654}{17654}=$− 1
(vi) (−729) ÷ (− 27) = $\frac{\left|-729\right|}{\left|-27\right|}=\frac{729}{27}=$ 27
(vii) 21590 ÷ − 10 = $-\frac{\left|21590\right|}{\left|-10\right|}=-\frac{21590}{10}=$− 2159
(viii) 0 ​ ÷ ​(−135) = $-\frac{\left|0\right|}{\left|-135\right|}=-\frac{0}{135}=0$
