<h3>Percentage</h3>

The percentage is the given definition for a fraction whose denominator is equal to 100. It is represented by %. See the following example:

$\frac{50}{100} =0.5*100=50%$

The percentage is considered a math tool with several applications and areas, for example: medicine, engineering, investments, supermarkets, drugstores,banks etc.

The exercise asks you the value of A and it gives you the value (900) that represents 130%A. Thus, you should write an equality between the division the percentage and the variable A by 100 with the value 900.

You should follow the steps below.

$\frac{130*A}{100}=900\\ \\ 130A=90000\\ \\ A=\frac{90000}{130} =692.31$
