Attending school

Huang lives 1/4 of a mile from school, while Lily lives 2/3 of a mile from school. How much further does Lily live from school than Huang?

Correct answer:

x =  5/12 mi

Step-by-step explanation:

$$\begin{gathered} h=\frac{1}{4}=0.25\text{mi} \\ l=\frac{2}{3}\doteq 0.6667\text{mi} \\ x=l-h=\frac{2}{3}-\frac{1}{4}=\frac{8}{12}-\frac{3}{12}=\frac{8-3}{12}=\frac{5}{12}=\frac{5}{12}\text{mi}=0.4167\text{mi} \end{gathered}$$
