Question

explain the 15percentage of 250

Answer 1

1. We assume, that the number 250 is 100% - because it's the output value of the task. 
2. We assume, that x is the value we are looking for. 
3. If 250 is 100%, so we can write it down as 250=100%. 
4. We know, that x is 15% of the output value, so we can write it down as x=15%. 
5. Now we have two simple equations:
1) 250=100%
2) x=15%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
250/x=100%/15%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 15% of 250

250/x=100/15
(250/x)*x=(100/15)*x       - we multiply both sides of the equation by x
250=6.66666666667*x       - we divide both sides of the equation by (6.66666666667) to get x
250/6.66666666667=x 
37.5=x 
x=37.5

now we have: 
15% of 250=37.5

Answer 2

15%of250=15/100)(250
=3/20)(250
=3/2)(25
=37.5
