What is 1.21000001E-11% of 100 - 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 100 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 is 100%, so we can write it down as 100=100%.
4. We know, that x is 1.21000001E-11% of the output value, so we can write it down as x=1.21000001E-11%.
5. Now we have two simple equations:
1) 100=100%
2) x=1.21000001E-11%
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=100%/1.21000001E-11%
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 1.21000001E-11% of 100

100/x=100/1.21000001E-11
(100/x)*x=(100/1.21000001E-11)*x       - we multiply both sides of the equation by x
100=8.26446274162E+12*x       - we divide both sides of the equation by (8.26446274162E+12) to get x
100/8.26446274162E+12=x
1.21000001E-11=x
x=1.21000001E-11

now we have:
1.21000001E-11% of 100=1.21000001E-11
