2145.12 is what percent of 77100 - 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 77100 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 77100, so we can write it down as 100%=77100.
4. We know, that x% equals 2145.12 of the output value, so we can write it down as x%=2145.12.
5. Now we have two simple equations:
1) 100%=77100
2) x%=2145.12
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%=77100/2145.12
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2145.12 is what percent of 77100

100%/x%=77100/2145.12
(100/x)*x=(77100/2145.12)*x       - we multiply both sides of the equation by x
100=35.942045200269*x       - we divide both sides of the equation by (35.942045200269) to get x
100/35.942045200269=x
2.7822568093385=x
x=2.7822568093385

now we have:
