Answer 1

Answer:

White: 1/4

Red: 1/3

Black if 24 counters: 5/12 or 10 counters.

Step-by-step explanation:

White is 90 degrees. A circle in total has 360 degrees.

$\frac{90}{360} = \frac{1}{4}$ so the fraction of whites in the bag is 1/4 or 0.25

Same logic with the red:

$\frac{120}{360} = \frac{1}{3}$ The fraction is 1/3 or 0.33(3)

Now, if the white is 1/4 and the red is 1/3 then the fraction of blacks is:

$1 or \frac{12}{12} - \frac{1}{3} -\frac{1}{4} =$

$\frac{12}{12} -\frac{4}{12} -\frac{3}{12} = \frac{5}{12}$

If total is 24 then all we have to do is find 5/12 of 24.

$\frac{5}{12} * 24 = 10$.

And that's the answer to the third question
