What is 9.5 percent of 2.1 - 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 2.1 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 2.1 is 100%, so we can write it down as 2.1=100%.
4. We know, that x is 9.5% of the output value, so we can write it down as x=9.5%.
5. Now we have two simple equations:
1) 2.1=100%
2) x=9.5%
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:
2.1/x=100%/9.5%
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 9.5% of 2.1

2.1/x=100/9.5
(2.1/x)*x=(100/9.5)*x       - we multiply both sides of the equation by x
2.1=10.526315789474*x       - we divide both sides of the equation by (10.526315789474) to get x
2.1/10.526315789474=x
0.1995=x
x=0.1995

now we have:
9.5% of 2.1=0.1995
