6.84 is what percent of 10.5 - 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 10.5 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 10.5, so we can write it down as 100%=10.5.
4. We know, that x% equals 6.84 of the output value, so we can write it down as x%=6.84.
5. Now we have two simple equations:
1) 100%=10.5
2) x%=6.84
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%=10.5/6.84
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 6.84 is what percent of 10.5

100%/x%=10.5/6.84
(100/x)*x=(10.5/6.84)*x       - we multiply both sides of the equation by x
100=1.5350877192982*x       - we divide both sides of the equation by (1.5350877192982) to get x
100/1.5350877192982=x
65.142857142857=x
x=65.142857142857

now we have:
6.84 is 65.142857142857% of 10.5
