What is 5.1 percent of 4.5 - 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 4.5 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 4.5 is 100%, so we can write it down as 4.5=100%.
4. We know, that x is 5.1% of the output value, so we can write it down as x=5.1%.
5. Now we have two simple equations:
1) 4.5=100%
2) x=5.1%
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:
4.5/x=100%/5.1%
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 5.1% of 4.5

4.5/x=100/5.1
(4.5/x)*x=(100/5.1)*x       - we multiply both sides of the equation by x
4.5=19.607843137255*x       - we divide both sides of the equation by (19.607843137255) to get x
4.5/19.607843137255=x
0.2295=x
x=0.2295

now we have:
5.1% of 4.5=0.2295
