6.9 is what percent of 322 - 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 322 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 322, so we can write it down as 100%=322.
4. We know, that x% equals 6.9 of the output value, so we can write it down as x%=6.9.
5. Now we have two simple equations:
1) 100%=322
2) x%=6.9
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%=322/6.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 6.9 is what percent of 322

100%/x%=322/6.9
(100/x)*x=(322/6.9)*x       - we multiply both sides of the equation by x
100=46.666666666667*x       - we divide both sides of the equation by (46.666666666667) to get x
100/46.666666666667=x
2.1428571428571=x
x=2.1428571428571

now we have:
6.9 is 2.1428571428571% of 322
