What is 19.5 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 149 is 100%, so we can write it down as 149=100%.
4. We know, that x is 19.5% of the output value, so we can write it down as x=19.5%.
5. Now we have two simple equations:
1) 149=100%
2) x=19.5%
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:
149/x=100%/19.5%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 19.5% of 149

149/x=100/19.5
(149/x)*x=(100/19.5)*x       - we multiply both sides of the equation by x
149=5.1282051282051*x       - we divide both sides of the equation by (5.1282051282051) to get x
149/5.1282051282051=x
29.055=x
x=29.055

now we have:
19.5% of 149=29.055
