331.1 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 331.1 of the output value, so we can write it down as x%=331.1.
5. Now we have two simple equations:
1) 100%=430
2) x%=331.1
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%=430/331.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 331.1 is what percent of 430

100%/x%=430/331.1
(100/x)*x=(430/331.1)*x       - we multiply both sides of the equation by x
100=1.2987012987013*x       - we divide both sides of the equation by (1.2987012987013) to get x
100/1.2987012987013=x
77=x
x=77

now we have:
331.1 is 77% of 430
