A rational number is a number that can be written in the form $\frac{a}{b}$ where $b\neq 0$, I'm doing an exercise where the author asks: Is 5.96 a rational number?
I believe I should find one $a$ and one $b$ such that $\frac{a}{b}=5.96$ to prove it's rational, but I don't know how to search for these numbers, can you help me?
