65.3 is what percent of 210 - 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 210 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 210, so we can write it down as 100%=210.
4. We know, that x% equals 65.3 of the output value, so we can write it down as x%=65.3.
5. Now we have two simple equations:
1) 100%=210
2) x%=65.3
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%=210/65.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 65.3 is what percent of 210

100%/x%=210/65.3
(100/x)*x=(210/65.3)*x       - we multiply both sides of the equation by x
100=3.2159264931087*x       - we divide both sides of the equation by (3.2159264931087) to get x
100/3.2159264931087=x
31.095238095238=x
x=31.095238095238

now we have:
65.3 is 31.095238095238% of 210
