Mathematics

Set up a proportion. X is the number you're looking for:

$\frac{3}{x}=\frac{4}{100}$

This relates 3 to x as 4 percent relates to 100. Simplify the 4 and the 100 to 1 and 25, cross multiply, and solve for x:

$\frac{3}{x}=\frac{4}{100}\\\frac{3}{x}=\frac{1}{25}\\(x)(1)=(3)(25)\\x=75$

3 is 4% of 75.
