69.3 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 69.3 of the output value, so we can write it down as x%=69.3.
5. Now we have two simple equations:
1) 100%=210
2) x%=69.3
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%=210/69.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 69.3 is what percent of 210

100%/x%=210/69.3
(100/x)*x=(210/69.3)*x       - we multiply both sides of the equation by x
100=3.030303030303*x       - we divide both sides of the equation by (3.030303030303) to get x
100/3.030303030303=x
33=x
x=33

now we have:
69.3 is 33% of 210
