87 is what percent of 1814 - 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 1814 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 1814, so we can write it down as 100%=1814.
4. We know, that x% equals 87 of the output value, so we can write it down as x%=87.
5. Now we have two simple equations:
1) 100%=1814
2) x%=87
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%=1814/87
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 87 is what percent of 1814

100%/x%=1814/87
(100/x)*x=(1814/87)*x       - we multiply both sides of the equation by x
100=20.850574712644*x       - we divide both sides of the equation by (20.850574712644) to get x
100/20.850574712644=x
4.7960308710033=x
x=4.7960308710033

now we have:
87 is 4.7960308710033% of 1814
