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

By using the listing method, the number of possible uniforms that Brilliant Spa can choose from is equal to 9 uniforms.

<h3>What is a listing method?</h3>

In Mathematics, a listing method can be defined as a technique which is used to list all the elements or members of a data set, while separating each of them with a comma and enclosing the data set within curly braces.

From the information provided above, we have the following points:

Polo shirts come with color yellow, red, and green.

The pants come with color black, blue, and white.

By using the listing method, a list of all the elements in this data set is given by:

List = {(yellow, black), (yellow, blue), (yellow, white), (red, black), (red, blue), (red, white), (green, black), (green, blue), (green, white)}

Number of possible uniforms = 9 uniforms.

X - the number of plants in 8 in pots
y - the number of plants in 10 in pots

$x+y=6\\
5x+8y=36\\\\
x=6-y\\
5x+8y=36\\
5(6-y)+8y=36\\
30-5y+8y=36\\
3y=6\\
y=2\\\\
x+2=6\\
x=4$

4 plants in 8 in pots and 2 in 10 in pots.
