40 is what percent of 223.653 - 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 223.653 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 223.653, so we can write it down as 100%=223.653.
4. We know, that x% equals 40 of the output value, so we can write it down as x%=40.
5. Now we have two simple equations:
1) 100%=223.653
2) x%=40
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%=223.653/40
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 40 is what percent of 223.653

100%/x%=223.653/40
(100/x)*x=(223.653/40)*x       - we multiply both sides of the equation by x
100=5.591325*x       - we divide both sides of the equation by (5.591325) to get x
100/5.591325=x
17.884848403554=x
x=17.884848403554

now we have:
40 is 17.884848403554% of 223.653
