349.88 is what percent of 406.4 - 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 406.4 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 406.4, so we can write it down as 100%=406.4.
4. We know, that x% equals 349.88 of the output value, so we can write it down as x%=349.88.
5. Now we have two simple equations:
1) 100%=406.4
2) x%=349.88
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%=406.4/349.88
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 349.88 is what percent of 406.4

100%/x%=406.4/349.88
(100/x)*x=(406.4/349.88)*x       - we multiply both sides of the equation by x
100=1.1615410998056*x       - we divide both sides of the equation by (1.1615410998056) to get x
100/1.1615410998056=x
86.092519685039=x
x=86.092519685039

now we have:
349.88 is 86.092519685039% of 406.4
