170.69 is what percent of 321 - 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 321 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 321, so we can write it down as 100%=321.
4. We know, that x% equals 170.69 of the output value, so we can write it down as x%=170.69.
5. Now we have two simple equations:
1) 100%=321
2) x%=170.69
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%=321/170.69
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 170.69 is what percent of 321

100%/x%=321/170.69
(100/x)*x=(321/170.69)*x       - we multiply both sides of the equation by x
100=1.8806022614096*x       - we divide both sides of the equation by (1.8806022614096) to get x
100/1.8806022614096=x
53.17445482866=x
x=53.17445482866

now we have:
170.69 is 53.17445482866% of 321
