Question

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

Answer 1

Pairs of integers.

The five pairs of integers $(a,b)$ such that $a÷b=-3$ are,

$$\begin{gathered} a.(3,-1)\mathrm{because}\left(3\right)÷(-1)=-3 \\ b.(-12,4)\mathrm{because}(-12)÷4=-3 \\ c.(-15,5)\mathrm{because}(-15)÷5=-3 \\ d.(24,-8)\mathrm{because}24÷(-8)=-3 \\ e.(-45,15)\mathrm{because}(-45)÷15=-3 \end{gathered}$$

Hence, five pairs of integers are $(3,-1),(-12,4),(-15,5),(24,-8)\mathrm{and}(-45,15)$.
