6.3 is what percent of 221 - 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 221 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 221, so we can write it down as 100%=221.
4. We know, that x% equals 6.3 of the output value, so we can write it down as x%=6.3.
5. Now we have two simple equations:
1) 100%=221
2) x%=6.3
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%=221/6.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 6.3 is what percent of 221

100%/x%=221/6.3
(100/x)*x=(221/6.3)*x       - we multiply both sides of the equation by x
100=35.079365079365*x       - we divide both sides of the equation by (35.079365079365) to get x
100/35.079365079365=x
2.8506787330317=x
x=2.8506787330317

now we have:
6.3 is 2.8506787330317% of 221
