7.9 is what percent of 539.5 - 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 539.5 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 539.5, so we can write it down as 100%=539.5.
4. We know, that x% equals 7.9 of the output value, so we can write it down as x%=7.9.
5. Now we have two simple equations:
1) 100%=539.5
2) x%=7.9
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%=539.5/7.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.9 is what percent of 539.5

100%/x%=539.5/7.9
(100/x)*x=(539.5/7.9)*x       - we multiply both sides of the equation by x
100=68.291139240506*x       - we divide both sides of the equation by (68.291139240506) to get x
100/68.291139240506=x
1.4643188137164=x
x=1.4643188137164

now we have:
7.9 is 1.4643188137164% of 539.5
