0.15 is what percent of 6.435 - 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 6.435 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 6.435, so we can write it down as 100%=6.435.
4. We know, that x% equals 0.15 of the output value, so we can write it down as x%=0.15.
5. Now we have two simple equations:
1) 100%=6.435
2) x%=0.15
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%=6.435/0.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.15 is what percent of 6.435

100%/x%=6.435/0.15
(100/x)*x=(6.435/0.15)*x       - we multiply both sides of the equation by x
100=42.9*x       - we divide both sides of the equation by (42.9) to get x
100/42.9=x
2.3310023310023=x
x=2.3310023310023

now we have:
0.15 is 2.3310023310023% of 6.435
