15.2 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 15.2 of the output value, so we can write it down as x%=15.2.
5. Now we have two simple equations:
1) 100%=149
2) x%=15.2
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%=149/15.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.2 is what percent of 149

100%/x%=149/15.2
(100/x)*x=(149/15.2)*x       - we multiply both sides of the equation by x
100=9.8026315789474*x       - we divide both sides of the equation by (9.8026315789474) to get x
100/9.8026315789474=x
10.201342281879=x
x=10.201342281879

now we have:
15.2 is 10.201342281879% of 149
