$$30\text{/hour}$	$=3000\ \text{cents/}60\ \text{minutes}$
	$= \dfrac{3000}{60}\ \text{cents/}\dfrac{60}{60}\ \text{minutes}$
	$=50\ \text{cents/}\text{minute}$

\($30\text{/hour}\)	\(=3000\ \text{cents/}60\ \text{minutes}\)
	\(= \dfrac{3000}{60}\ \text{cents/}\dfrac{60}{60}\ \text{minutes}\)
	\(=50\ \text{cents/}\text{minute}\)
