53.3 is what percent of 213.2 - 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 213.2 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 213.2, so we can write it down as 100%=213.2.
4. We know, that x% equals 53.3 of the output value, so we can write it down as x%=53.3.
5. Now we have two simple equations:
1) 100%=213.2
2) x%=53.3
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%=213.2/53.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 53.3 is what percent of 213.2

100%/x%=213.2/53.3
(100/x)*x=(213.2/53.3)*x       - we multiply both sides of the equation by x
100=4*x       - we divide both sides of the equation by (4) to get x
100/4=x
25=x
x=25

now we have:
53.3 is 25% of 213.2
