What is 5.15 percent of 905 - 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 905 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 905 is 100%, so we can write it down as 905=100%.
4. We know, that x is 5.15% of the output value, so we can write it down as x=5.15%.
5. Now we have two simple equations:
1) 905=100%
2) x=5.15%
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:
905/x=100%/5.15%
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 5.15% of 905

905/x=100/5.15
(905/x)*x=(100/5.15)*x       - we multiply both sides of the equation by x
905=19.417475728155*x       - we divide both sides of the equation by (19.417475728155) to get x
905/19.417475728155=x
46.6075=x
x=46.6075

now we have:
5.15% of 905=46.6075
