What is 5 percent of 17.309 - 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 17.309 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 17.309 is 100%, so we can write it down as 17.309=100%.
4. We know, that x is 5% of the output value, so we can write it down as x=5%.
5. Now we have two simple equations:
1) 17.309=100%
2) x=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:
17.309/x=100%/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 5% of 17.309

17.309/x=100/5
(17.309/x)*x=(100/5)*x       - we multiply both sides of the equation by x
17.309=20*x       - we divide both sides of the equation by (20) to get x
17.309/20=x
0.86545=x
x=0.86545

now we have:
5% of 17.309=0.86545
