Hey! We can solve this exercise using Rule of Three, look:
[tex]\frac{1,845}{4,500}=\frac{x}{100}[/tex]Multiplying across, we obtain:
[tex]\begin{gathered} 4,500\cdot x=1,845\cdot100 \\ 4,500x=184,500 \\ x=\frac{184,500}{4,500} \\ \\ x=41\text{ per cent} \end{gathered}[/tex]So, the answer will be 41%.
