1. Divide:

(1) 102 by 17

(ii)-85 by 5

(iii)-161 by-23

(iv) 76 by-19

(v) 17654 by-17654


Solution:

(i) Given 102 by 17

We can write given question as 102 +17

102+17= |102/17| = |102|/|17| [by applying the mod]

= 102/17 = 6

(ii) Given -85 by 5

We can write given question as -85+5 85+5=1-85/511-851/151 [by applying the mod]
=-85/5=-17

(iii) Given-161 by-23

We can write given question as -161 +-23 -161+-23=1-161/-231-1-1611/1-23] [by applying the mod]
=161/23=7

(iv) Given 76 by-19

We can write given question as 76 +-19 76+-19 176/-191 = 1761/1-191 [by applying the mod]
=76/-19=-4

(v) Given 17654 by-17654

We can write given question as 17654 +-17654 17654-17654 117654/-17654]=1176541/1-17654| [by applying the mod]
=17654/-17654=-1​
