Write the following decimal number in its equivalent fraction form.

Alecsey [184]

Answer:

-0.6666.... = - $\frac{2}{3}$

Step-by-step explanation:

Repeating decimals can be written as either 0.6666..., or as 0.6 with a small line over the top of the 6 to indicate it repeats. Repeating fractions are not put into fractions in the traditional way. If we had the terminating decimal 0.4, then we know to put the 4 over 10 and reduce:

$\frac{4}{10}=\frac{2}{5}$

However, with repeating decimals, instead of putting the number of the decimal over a value of 10, we put it over a value of 9. So, for the equivalent fraction form of -0.6 (repeating) we would get:

$\frac{6}{9}=-\frac{2}{3}$

How do you solve cos((π/6)x)=0

zlopas [31]

$\bf cos\left( \frac{\pi }{6}x \right)=0\implies cos^{-1}\left[ cos\left( \frac{\pi }{6}x \right) \right]=cos^{-1}(0)
\\\\\\
\cfrac{\pi x}{6}=cos^{-1}(0)\implies \cfrac{\pi x}{6}=
\begin{cases}
\frac{\pi }{2}\\\\
\frac{3\pi }{2}
\end{cases}\\\\
-------------------------------$

$\bf \cfrac{\pi x}{6}=\cfrac{\pi }{2}\implies \pi x=\cfrac{6\pi }{2}\implies x=\cfrac{6\pi }{2\pi }
\implies \measuredangle x=\stackrel{radians}{3}\\\\
-------------------------------\\\\
\cfrac{\pi x}{6}=\cfrac{3\pi }{2}\implies\pi x=\cfrac{18\pi }{2}\implies x=\cfrac{18\pi }{2\pi }\implies \measuredangle x=\stackrel{radians}{9}$
