102.1 is what percent of 116.9 - 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 116.9 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 116.9, so we can write it down as 100%=116.9.
4. We know, that x% equals 102.1 of the output value, so we can write it down as x%=102.1.
5. Now we have two simple equations:
1) 100%=116.9
2) x%=102.1
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%=116.9/102.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 102.1 is what percent of 116.9

100%/x%=116.9/102.1
(100/x)*x=(116.9/102.1)*x       - we multiply both sides of the equation by x
100=1.1449559255632*x       - we divide both sides of the equation by (1.1449559255632) to get x
100/1.1449559255632=x
87.339606501283=x
x=87.339606501283

now we have:
102.1 is 87.339606501283% of 116.9
