19.3 is what percent of 0.45 - 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 0.45 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 100% equals 0.45, so we can write it down as 100%=0.45.
4. We know, that x% equals 19.3 of the output value, so we can write it down as x%=19.3.
5. Now we have two simple equations:
1) 100%=0.45
2) x%=19.3
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%=0.45/19.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19.3 is what percent of 0.45

100%/x%=0.45/19.3
(100/x)*x=(0.45/19.3)*x       - we multiply both sides of the equation by x
100=0.023316062176166*x       - we divide both sides of the equation by (0.023316062176166) to get x
100/0.023316062176166=x
4288.8888888889=x
x=4288.8888888889

now we have:
19.3 is 4288.8888888889% of 0.45
