171.9 is what percent of 1699 - 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 1699 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 100% equals 1699, so we can write it down as 100%=1699.
4. We know, that x% equals 171.9 of the output value, so we can write it down as x%=171.9.
5. Now we have two simple equations:
1) 100%=1699
2) x%=171.9
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:
100%/x%=1699/171.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 171.9 is what percent of 1699

100%/x%=1699/171.9
(100/x)*x=(1699/171.9)*x       - we multiply both sides of the equation by x
100=9.8836532867946*x       - we divide both sides of the equation by (9.8836532867946) to get x
100/9.8836532867946=x
10.117716303708=x
x=10.117716303708

now we have:
171.9 is 10.117716303708% of 1699
