I attached a picture, see if you can see what I'm doing. Basically, I start by squaring everything to get rid of the radical, but just remember at the end to always, always check your answers, because squaring your answers could get rid of some negative numbers that could result in imaginary answers. The answer I came up with was a=5,-2

Which fraction and equivalent decimal correctly shows the ratio of shaded circles to all circles?

sergeinik [125]

Shaded circles = 4
Total circles = 12

$\frac{shaded~circles}{total~circles}$ = $\frac{4}{12}$

$\frac{4}{12}$ as a simplified expression = $\frac{2}{6}$
We can simplify it even more = $\frac{1}{3}$

Fraction = $\frac{1}{3}$

Equivalent decimal = 1 ÷ 3 = 0.33
