321.59 is what percent of 430 - 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 430 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 430, so we can write it down as 100%=430.
4. We know, that x% equals 321.59 of the output value, so we can write it down as x%=321.59.
5. Now we have two simple equations:
1) 100%=430
2) x%=321.59
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%=430/321.59
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 321.59 is what percent of 430

100%/x%=430/321.59
(100/x)*x=(430/321.59)*x       - we multiply both sides of the equation by x
100=1.3371062533039*x       - we divide both sides of the equation by (1.3371062533039) to get x
100/1.3371062533039=x
74.788372093023=x
x=74.788372093023

now we have:
321.59 is 74.788372093023% of 430
