What is 40.5 percent of 117 - 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 117 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 117 is 100%, so we can write it down as 117=100%.
4. We know, that x is 40.5% of the output value, so we can write it down as x=40.5%.
5. Now we have two simple equations:
1) 117=100%
2) x=40.5%
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:
117/x=100%/40.5%
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 40.5% of 117

117/x=100/40.5
(117/x)*x=(100/40.5)*x       - we multiply both sides of the equation by x
117=2.4691358024691*x       - we divide both sides of the equation by (2.4691358024691) to get x
117/2.4691358024691=x
47.385=x
x=47.385

now we have:
40.5% of 117=47.385
