$250$

$1$ . Start by making a "let" statement to let a variable represent the number.

Let $x$ represent a number.

$2$ . Create an algebraic expression. Remember to express $75%$ as a decimal.

$0.75x=187.5$

$3$ . Divide both sides by $0.75$ to solve for $x$ .

$color(red)((color(black)(0.75x))/0.75)=color(red)(color(black)(187.5)/0.75)$

$color(green)(|bar(ul(color(white)(a/a)x=250color(white)(a/a)|)))$

$:.$ , the number is $250$ .
