36

Answer 2

Answer:

27 is 75% of 36

Step-by-step explanation:

METHOD 1:

$\begin{array}{ccc}27&-&75\%\\\\x&-&100\%\end{array}\qquad|\text{cross multiply}$

$(75)(x)=(27)(100)\\\\75x=2700\qquad|\text{divide both sides by 75}\\\\x=36$

METHOD 2:

$n$-a number

$p\%=\dfrac{p}{100}\\\\75\%=\dfrac{75}{100}=0.75$

75% of a number is 27:

$0.75\cdot n=27\qquad|\text{divide both sides by 0.75}\\\\n=36$
