• A. $\frac{3}{10}$
• B. $\frac{10}{3}$
• C. $\frac{6}{20}$

Answer 1

The correct option is A $\frac{3}{10}$

Let's rewrite the numerator and the denominator into its factors

$\frac{12}{40}=\frac{2\times 2\times 3}{2\times 2\times 2\times 5}=\frac{3}{2\times 5}=\frac{3}{10}$

So, the simplest form of $\frac{12}{40}$ is $\frac{3}{10}.$
