Question

Find the quotient and remainder when a is divided by b in the following
cases (i)a =−12 , b = 5.

Answer 1

Answer:

By Euclid's division lemma

For any given integer a and b there exist unique integer q and r such that

a=bq+r where a=dividend, b= divisor,q=quotient and r=remainder

Here we have a=12 and b=-5 there exist unique

Integer q and r such that

12=(-5)(-2)+(2)

Hence quotient (q)=-2and remainder (r)=2
