What is 42.5 percent of 17 - 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 17 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 17 is 100%, so we can write it down as 17=100%.
4. We know, that x is 42.5% of the output value, so we can write it down as x=42.5%.
5. Now we have two simple equations:
1) 17=100%
2) x=42.5%
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:
17/x=100%/42.5%
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 42.5% of 17

17/x=100/42.5
(17/x)*x=(100/42.5)*x       - we multiply both sides of the equation by x
17=2.3529411764706*x       - we divide both sides of the equation by (2.3529411764706) to get x
17/2.3529411764706=x
7.225=x
x=7.225

now we have:
42.5% of 17=7.225
