6.9 is what percent of 75.6 - 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 75.6 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 75.6, so we can write it down as 100%=75.6.
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%=75.6
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%=75.6/6.9
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 75.6

100%/x%=75.6/6.9
(100/x)*x=(75.6/6.9)*x       - we multiply both sides of the equation by x
100=10.95652173913*x       - we divide both sides of the equation by (10.95652173913) to get x
100/10.95652173913=x
9.1269841269841=x
x=9.1269841269841

now we have:
6.9 is 9.1269841269841% of 75.6
