Method 1:

[tex]\dfrac{45}{75}=\dfrac{45:15}{75:15}=\dfrac{3}{5}\\\\\dfrac{3}{5}\cdot100\%=\dfrac{300}{5}\%=60\%[/tex]

Answer: 45 is 60% of 75.

Method 2:

[tex]\begin{array}{ccc}75&-&100\%\\45&-&p\%\end{array}\ \ \ |\text{cross multiply}\\\\p\cdot75=45\cdot100\ \ \ \ |\text{divide both sides by 75}\\\\p=\dfrac{4500}{75}\\\\p=60\\\\Answer:\ 60\%[/tex]

what percent of 75 is 45

  n     ÷ 100    *   75 = 45

  n                  * [tex]\frac{75}{100}[/tex] = 45

  n              * [tex](\frac{100}{75})[/tex] [tex]\frac{75}{100}[/tex] = 45 [tex](\frac{100}{75})[/tex]

 n                              =  [tex]\frac{4500}{75}[/tex]

 n                              = 60

Answer: 60%
