What is 2.857 percent of 225 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 225 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 225 is 100%, so we can write it down as 225=100%.
4. We know, that x is 2.857% of the output value, so we can write it down as x=2.857%.
5. Now we have two simple equations:
1) 225=100%
2) x=2.857%
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:
225/x=100%/2.857%
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 2.857% of 225

225/x=100/2.857
(225/x)*x=(100/2.857)*x       - we multiply both sides of the equation by x
225=35.001750087504*x       - we divide both sides of the equation by (35.001750087504) to get x
225/35.001750087504=x
6.42825=x
x=6.42825

now we have:
2.857% of 225=6.42825
