35 is what percent of 128.5 - 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 128.5 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 100% equals 128.5, so we can write it down as 100%=128.5.
4. We know, that x% equals 35 of the output value, so we can write it down as x%=35.
5. Now we have two simple equations:
1) 100%=128.5
2) x%=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%=128.5/35
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 35 is what percent of 128.5

100%/x%=128.5/35
(100/x)*x=(128.5/35)*x       - we multiply both sides of the equation by x
100=3.6714285714286*x       - we divide both sides of the equation by (3.6714285714286) to get x
100/3.6714285714286=x
27.237354085603=x
x=27.237354085603

now we have:
35 is 27.237354085603% of 128.5
