432.6 is what percent of 4200 - 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 4200 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 4200, so we can write it down as 100%=4200.
4. We know, that x% equals 432.6 of the output value, so we can write it down as x%=432.6.
5. Now we have two simple equations:
1) 100%=4200
2) x%=432.6
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%=4200/432.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 432.6 is what percent of 4200

100%/x%=4200/432.6
(100/x)*x=(4200/432.6)*x       - we multiply both sides of the equation by x
100=9.7087378640777*x       - we divide both sides of the equation by (9.7087378640777) to get x
100/9.7087378640777=x
10.3=x
x=10.3

now we have:
432.6 is 10.3% of 4200
