Step 1 :Write the percentage as a fraction with the percentage as the numerator and 100 as the denominator: \(\frac{48}{100}\).
Step 2 :Simplify the fraction to its lowest terms by finding the greatest common divisor (GCD) of the numerator and the denominator and dividing both by it: \(\frac{24}{50}\), \(2 \frac{1}{12}\), \(\frac{12}{25}\).
Step 3 :The fraction in lowest form for $48 \%$ is \(\boxed{\frac{12}{25}}\).
