10.3 is what percent of 213.1 - 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 213.1 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 213.1, so we can write it down as 100%=213.1.
4. We know, that x% equals 10.3 of the output value, so we can write it down as x%=10.3.
5. Now we have two simple equations:
1) 100%=213.1
2) x%=10.3
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%=213.1/10.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 10.3 is what percent of 213.1

100%/x%=213.1/10.3
(100/x)*x=(213.1/10.3)*x       - we multiply both sides of the equation by x
100=20.68932038835*x       - we divide both sides of the equation by (20.68932038835) to get x
100/20.68932038835=x
4.8334115438761=x
x=4.8334115438761

now we have:
10.3 is 4.8334115438761% of 213.1
