Answer :
Let x be "the number that makes the equation true":
[tex]0.54+13,500=\frac{x}{100}+13,500[/tex]Solve x in the equation above:
As 13,500 is being added in both sides of the equation you can eliminate it:
[tex]0.54=\frac{x}{100}[/tex]Multiply both sides of the equation by 100:
[tex]\begin{gathered} 100\cdot0.54=100\cdot\frac{x}{100} \\ \\ 54=x \end{gathered}[/tex]Then, the number that makes the equation true is 54
