Question

What number is 25 percent of 400?

Answer 1

400 x .25 = x

Change the 25% into a decimal

400 x .25 = 100

Answer 2

1. To make the question easy lets think 400 is 100%. 

2. Lets think that x is the value we are trying to find out. 

3. If 400 is 100%, we can write it as 400 = 100%. 

4.  X is 25% of the value, so we can write x=25%. 

5. Now we have two equations to solve:

1) 400=100%

2) x=25%

 we can make 400=100% and x=25%  to

400/x=100%/25%

6. Now we can solve the equation 

7. 25% of 400 = 

400/x=100/25

(400/x)*x=(100/25)*x  
                                             multiply equation by x
400=4*x  
                                    divide equation by (4) to get x
400/4=x 

100=x 






The answer is 
25% of 400=100
