Question

Which of the following circles have half of their area colored green?
(Note: There can be more than one correct answer.)

• A.
• B.
• C.
• D.

Answer 1

Answer: (B), (D)

Fractions of the circles colored green:
Dividing the numerator and denominator of $\frac{2}{4}$ by $2$, we get $\frac{1}{2}$
Dividing the numerator and denominator of $\frac{4}{8}$ by $4$, we get$\frac{1}{2}$
Since $\frac{2}{4}$ and $\frac{4}{8}$ are equivalent fractions of $\frac{1}{2}$, circle $b$ and circle $d$ have half of their areas colored green.
