$7$% $=.07$ or $\frac{7}{100}$. So $7$% of a number can be given by $.07 x$ or $\frac{7}{100} x$. The "of" here means you multiply. So your equation is: $$\frac{7}{100}x=100000$$ – Zhoe Feb 13 '14 at 1:07

$\frac{7}{100}x=100000\\ x=10000000/7\approx 1428571.42857$
$.07\cdot x=100000$, now solve for $x$.
