Liz makes

Liz makes footprints in the snow with her boots that are 3/4 foot long. Liz's feet are only 2/3 foot long. What expression can be used to find out how much longer Liz's boot prints are than her feet?

Final Answer:

x =  1/12 ft

Step-by-step explanation:

$$\begin{gathered} a=\frac{3}{4}=0.75\text{ft} \\ b=\frac{2}{3}\doteq 0.6667\text{ft} \\ x=a-b=\frac{3}{4}-\frac{2}{3}=\frac{9}{12}-\frac{8}{12}=\frac{9-8}{12}=\frac{1}{12}=\frac{1}{12}\text{ft}=0.0833\text{ft} \end{gathered}$$
