17.9 is what percent of 149 - 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 149 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 149, so we can write it down as 100%=149.
4. We know, that x% equals 17.9 of the output value, so we can write it down as x%=17.9.
5. Now we have two simple equations:
1) 100%=149
2) x%=17.9
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%=149/17.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.9 is what percent of 149

100%/x%=149/17.9
(100/x)*x=(149/17.9)*x       - we multiply both sides of the equation by x
100=8.3240223463687*x       - we divide both sides of the equation by (8.3240223463687) to get x
100/8.3240223463687=x
12.013422818792=x
x=12.013422818792

now we have:
17.9 is 12.013422818792% of 149
