7.15 is what percent of 7.3 - 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 7.3 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 7.3, so we can write it down as 100%=7.3.
4. We know, that x% equals 7.15 of the output value, so we can write it down as x%=7.15.
5. Now we have two simple equations:
1) 100%=7.3
2) x%=7.15
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%=7.3/7.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.15 is what percent of 7.3

100%/x%=7.3/7.15
(100/x)*x=(7.3/7.15)*x       - we multiply both sides of the equation by x
100=1.020979020979*x       - we divide both sides of the equation by (1.020979020979) to get x
100/1.020979020979=x
97.945205479452=x
x=97.945205479452

now we have:
7.15 is 97.945205479452% of 7.3
