67.49 is what percent of 170 - 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 170 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 170, so we can write it down as 100%=170.
4. We know, that x% equals 67.49 of the output value, so we can write it down as x%=67.49.
5. Now we have two simple equations:
1) 100%=170
2) x%=67.49
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%=170/67.49
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 67.49 is what percent of 170

100%/x%=170/67.49
(100/x)*x=(170/67.49)*x       - we multiply both sides of the equation by x
100=2.5188916876574*x       - we divide both sides of the equation by (2.5188916876574) to get x
100/2.5188916876574=x
39.7=x
x=39.7

now we have:
67.49 is 39.7% of 170
