Ski savings fraction

Adam is saving for new skis. In August, he saved two-sevenths of the total price, in September one-eighth of the total price, and in October two-thirds of the missing amount. Express as a fraction how much he still has left to save from the price of the skis.

Final Answer:

x =  11/56

Step-by-step explanation:

$$\begin{gathered} a=1-\frac{2}{7}-\frac{1}{8}=\frac{33}{56}\doteq 0.5893 \\ x=a-\frac{2}{3}\cdot a=\frac{33}{56}-\frac{2}{3}\cdot \frac{33}{56}=\frac{11}{56}=0.1964 \end{gathered}$$
