$775.08$ $775.08$

Explanation:

$968.85$ $968.85$ is $125 %$ $125%$ of what number?

Use the formula "is over of equal percent over 100# or

$\frac{is}{of} = \frac{%}{100}$ $"is"/"of" = "%"/100$

$\frac{968.85}{x} = \frac{125}{100}$ $968.85/x = 125/100$

Cross multiply

$125 x = 968.85 \cdot 100$ $125x=968.85 * 100$

$125 x = 96885$ $125x=96885$

$\frac{125 x}{125} = \frac{96885}{125} a a a$ $(125x)/125=96885/125color(white)(aaa)$ Divide both sides by 125

$x = 775.08$ $x=775.08$

Another way to solve the problem is to first change the percent to a decimal by dividing by 100 and then to recall that "is" means equal and "of" means multiply.

$\frac{125 %}{100} = 1.25$ $(125%)/100= 1.25$

$968.85 = 1.25 \cdot x$ $968.85= 1.25 * x$

$\frac{968.85}{1.25} = \frac{1.25 x}{1.25}$ $968.85/1.25 =(1.25x)/1.25$

$775.08 = x$ $775.08=x$
