Question

Which of the following option(s) is/are true for the given figure below.

• A. Fraction of the shaded portion out of the whole portion is $\frac{1}{2}.$
• B. Fraction of the shaded portion out of the whole portion is $\frac{2}{1}.$
• C. Fraction of the unshaded portion out of the whole portion is $\frac{1}{2}.$
• D. Fraction of the unshaded portion out of the whole portion is $\frac{2}{1}.$

Answer 1

Answer: (A), (C)

Fraction of the unshaded portion out of the whole portion is $\frac{1}{2}.$

Total number of portion in the given figure $=2$
Number of shaded portion $=1$
Number of unshaded portion $=1$

$\therefore$ Fraction of shaded portion out of the whole portion $=\frac{\text{Number of shaded portion}}{\text{Total number of portion}}$
$=\frac{1}{2}$

Fraction of unshaded portion out of the whole portion $=\frac{\text{Number of unshaded portion}}{\text{Total number of portion}}$
$=\frac{1}{2}$
