7.3 is what percent of 3.9 - 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 3.9 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 3.9, so we can write it down as 100%=3.9.
4. We know, that x% equals 7.3 of the output value, so we can write it down as x%=7.3.
5. Now we have two simple equations:
1) 100%=3.9
2) x%=7.3
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%=3.9/7.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.3 is what percent of 3.9

100%/x%=3.9/7.3
(100/x)*x=(3.9/7.3)*x       - we multiply both sides of the equation by x
100=0.53424657534247*x       - we divide both sides of the equation by (0.53424657534247) to get x
100/0.53424657534247=x
187.17948717949=x
x=187.17948717949

now we have:
7.3 is 187.17948717949% of 3.9
