2. Solution Steps

First, convert the percentage to a fraction by dividing by 100:

$42\% = \frac{42}{100}$.

Next, simplify the fraction by finding the greatest common divisor (GCD) of the numerator and the denominator. The GCD of 42 and 100 is

2. Divide both numerator and denominator by 2:

$\frac{42}{100} = \frac{42 \div 2}{100 \div 2} = \frac{21}{50}$.

Since 21 and 50 do not share any common factors other than 1, the fraction $\frac{21}{50}$ is in simplest form.

3. Final Answer

21/50
