211 is what percent of 1878 - 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 1878 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 1878, so we can write it down as 100%=1878.
4. We know, that x% equals 211 of the output value, so we can write it down as x%=211.
5. Now we have two simple equations:
1) 100%=1878
2) x%=211
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%=1878/211
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 211 is what percent of 1878

100%/x%=1878/211
(100/x)*x=(1878/211)*x       - we multiply both sides of the equation by x
100=8.9004739336493*x       - we divide both sides of the equation by (8.9004739336493) to get x
100/8.9004739336493=x
11.235356762513=x
x=11.235356762513

now we have:
211 is 11.235356762513% of 1878
