Hello, Regan,

    I don't think you are stupid.  Let me help you with some examples, so that you understand the steps:

 

                                                                                                                                          10= 25% x_______?

1)  Underline or highlight the key words and numbers or percents in the problem:  For example, 10 is 25% of what number?

 

2) Ten is part of the whole.    10= 25% x__whole (larger amount)?      Usually, change percents into decimals or fractions, such as 25/100 since percent means part of 100.                   

 

3)   You can set up a proportion as follows:     Part/whole  =  Part/whole       10/x   =  25/100

 

4) Cross multiply:  10 * 100= 25*x          1000=25x    Now divide both sides of the equation by number next to x, the missing value or whole, and you will have the answer:     1000/25 = (25/25)  x    40=1x            25/25 =1

 

5)  You can work your  problem like this.  There are other methods.  I hope that this example helps.   Susan C.
