63.8 is what percent of 69.3 - 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 69.3 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 69.3, so we can write it down as 100%=69.3.
4. We know, that x% equals 63.8 of the output value, so we can write it down as x%=63.8.
5. Now we have two simple equations:
1) 100%=69.3
2) x%=63.8
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%=69.3/63.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 63.8 is what percent of 69.3

100%/x%=69.3/63.8
(100/x)*x=(69.3/63.8)*x       - we multiply both sides of the equation by x
100=1.0862068965517*x       - we divide both sides of the equation by (1.0862068965517) to get x
100/1.0862068965517=x
92.063492063492=x
x=92.063492063492

now we have:
63.8 is 92.063492063492% of 69.3
