15% of what number equals 12?

1 answer:

4 0

Percent means parts out of 100
15%=15/100=0.15
'of' means multiply

therefor
15% of x equals 12 means
0.15 times x=12
divide both sides by 0.15
x=80

the number is 80

$\bf ~~~~~~~~~~~~\textit{middle point of 2 points }\\\\
\begin{array}{ccccccccc}

% (a,b)
&J&(~ 0 &,& 2~)

\end{array}\qquad
% coordinates of midpoint

\left(\cfrac{x+0}{2}~~,~~\cfrac{y+2}{2} \right)=\stackrel{midpoint~T}{(0~,~5)}\implies 
\begin{cases}
\cfrac{x+0}{2}=0\\\\
\boxed{x=0}\\

\cfrac{y+2}{2}=5\\\\
y+2=10\\
\boxed{y=8}
