What is 7.21 percent of 103 - 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 103 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 103 is 100%, so we can write it down as 103=100%.
4. We know, that x is 7.21% of the output value, so we can write it down as x=7.21%.
5. Now we have two simple equations:
1) 103=100%
2) x=7.21%
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:
103/x=100%/7.21%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 7.21% of 103

103/x=100/7.21
(103/x)*x=(100/7.21)*x       - we multiply both sides of the equation by x
103=13.869625520111*x       - we divide both sides of the equation by (13.869625520111) to get x
103/13.869625520111=x
7.4263=x
x=7.4263

now we have:
7.21% of 103=7.4263
