0.35 is what percent of 0.9 - 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 0.9 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 0.9, so we can write it down as 100%=0.9.
4. We know, that x% equals 0.35 of the output value, so we can write it down as x%=0.35.
5. Now we have two simple equations:
1) 100%=0.9
2) x%=0.35
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%=0.9/0.35
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.35 is what percent of 0.9

100%/x%=0.9/0.35
(100/x)*x=(0.9/0.35)*x       - we multiply both sides of the equation by x
100=2.5714285714286*x       - we divide both sides of the equation by (2.5714285714286) to get x
100/2.5714285714286=x
38.888888888889=x
x=38.888888888889

now we have:
0.35 is 38.888888888889% of 0.9
