What is 30.615 percent of 15.45 - 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 15.45 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 15.45 is 100%, so we can write it down as 15.45=100%.
4. We know, that x is 30.615% of the output value, so we can write it down as x=30.615%.
5. Now we have two simple equations:
1) 15.45=100%
2) x=30.615%
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:
15.45/x=100%/30.615%
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 30.615% of 15.45

15.45/x=100/30.615
(15.45/x)*x=(100/30.615)*x       - we multiply both sides of the equation by x
15.45=3.2663726931243*x       - we divide both sides of the equation by (3.2663726931243) to get x
15.45/3.2663726931243=x
4.7300175=x
x=4.7300175

now we have:
30.615% of 15.45=4.7300175
