Question

450 is 7% of what number?

Answer 1

7% of x = 450
0.07×x=450
x=450/0.07
x=6428.6 to the nearest tenth (one decimal place)

Answer 2

$\text{Percent means number out of 100}$

$\dfrac{450}{x} =\dfrac{7}{100}$

      $\text{ - Multiply both sides of the equation by x}$

$\dfrac{450}{x}*x=\dfrac{7}{100} *x$

     $\text{-Divide both sides of the equation by 142857 to get x}$

$450=14.\overline{2857}*x$

$\dfrac{450}{14.2857} =x$

$x=31.5$  $\text{Solution}$
