Question

Write five pairs of integers $\left(a,b\right)$ such that $a÷b=-3.$ One such pairs is $\left(6,-2\right)$ because $6÷\left(-2\right)=\left(-3\right).$

Answer 1

Here, $a÷b=-3$
$\Rightarrow a=-3b$
Putting some different values to $b$, we get corresponding values of $a$ such as
(i) $b=1$, then
$a=-3b=-3\times 1=-3$
$(-3,1)$
(ii) $b=3$, then
$a=-3\times 3=-9$
$(-9,3)$ is a pair.
(iii) $b=4$, then $a=-3\times 4=-12$
Pair is $(-12,4)$
(iv) $b=5$, then $a=-3\times 5=-15$
Pair is $(-15,5)$
(v) $b=6$, then $a=-3\times 6=-18$
Pair is $(-18,6)$
