What is 10.5 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 10.5% of the output value, so we can write it down as x=10.5%.
5. Now we have two simple equations:
1) 149=100%
2) x=10.5%
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%/10.5%
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 10.5% of 149

149/x=100/10.5
(149/x)*x=(100/10.5)*x       - we multiply both sides of the equation by x
149=9.5238095238095*x       - we divide both sides of the equation by (9.5238095238095) to get x
149/9.5238095238095=x
15.645=x
x=15.645

now we have:
10.5% of 149=15.645
