15.4 is what percent of 229 - 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 229 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 229, so we can write it down as 100%=229.
4. We know, that x% equals 15.4 of the output value, so we can write it down as x%=15.4.
5. Now we have two simple equations:
1) 100%=229
2) x%=15.4
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%=229/15.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.4 is what percent of 229

100%/x%=229/15.4
(100/x)*x=(229/15.4)*x       - we multiply both sides of the equation by x
100=14.87012987013*x       - we divide both sides of the equation by (14.87012987013) to get x
100/14.87012987013=x
6.7248908296943=x
x=6.7248908296943

now we have:
15.4 is 6.7248908296943% of 229
