529 is what percent of 670 - 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 670 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 670, so we can write it down as 100%=670.
4. We know, that x% equals 529 of the output value, so we can write it down as x%=529.
5. Now we have two simple equations:
1) 100%=670
2) x%=529
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%=670/529
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 529 is what percent of 670

100%/x%=670/529
(100/x)*x=(670/529)*x       - we multiply both sides of the equation by x
100=1.2665406427221*x       - we divide both sides of the equation by (1.2665406427221) to get x
100/1.2665406427221=x
78.955223880597=x
x=78.955223880597

now we have:
529 is 78.955223880597% of 670
