Question

Find the odd one out.
$\frac{1}{2},\frac{3}{9},\frac{9}{27},\frac{4}{12}$

• A. $\frac{1}{2}$
• B. $\frac{3}{9}$
• C. $\frac{9}{27}$
• D. $\frac{4}{12}$

Answer 1

The correct option is A $\frac{1}{2}$

Let's simplify each fraction to find odd one:
To determine the given fractions are in its simplest form or not, we have to find the common factors in the numerator and the denominator.
Hence,
$\therefore \frac{1}{2}=\frac{1}{2}\frac{3}{9}=\frac{1\times 3}{3\times 3}=\frac{1}{3}\frac{9}{27}=\frac{3\times 3}{3\times 3\times 3}=\frac{1}{3}\frac{4}{12}=\frac{2\times 2}{2\times 2\times 3}=\frac{1}{3}$
All the fractions are equivalent to $\frac{1}{3}$ except $\frac{1}{2}$.
