What is 0.0077 percent of 0.157 - 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 0.157 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 0.157 is 100%, so we can write it down as 0.157=100%.
4. We know, that x is 0.0077% of the output value, so we can write it down as x=0.0077%.
5. Now we have two simple equations:
1) 0.157=100%
2) x=0.0077%
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:
0.157/x=100%/0.0077%
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 0.0077% of 0.157

0.157/x=100/0.0077
(0.157/x)*x=(100/0.0077)*x       - we multiply both sides of the equation by x
0.157=12987.012987013*x       - we divide both sides of the equation by (12987.012987013) to get x
0.157/12987.012987013=x
1.2089E-5=x
x=1.2089E-5

now we have:
0.0077% of 0.157=1.2089E-5
