\frac{25}{100}=\frac{5}{x}
Divide both sides by 100.
\frac{1}{4}=\frac{5}{x}
Reduce the fraction \frac{25}{100} to lowest terms by extracting and canceling out 25.
x=4\times 5
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 4x, the least common multiple of 4,x.
x=20
Multiply 4 and 5 to get 20.
