Find values of a and b such that a is a whole number, b is a rational number but not an integer, and a divided by b equals -8

Question

It doesnt have to be ONE number it can be whatever fits the equation.

anonymous · Answer

$$\frac{a}{b}=-8$$But b is rational so we can write it as a ratio of two intergers c and d:$$\frac{a}{\frac{c}{d}}=-8$$Thus$$ad=-8c$$You're just asked to find values which satisfy this.  Picking a=4, c=2 then d=-4.  So b=-2/4 of -1/2.  The solution is not unique.
