What is 5.0E+15 percent of 31.4848 - 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 31.4848 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 31.4848 is 100%, so we can write it down as 31.4848=100%.
4. We know, that x is 5.0E+15% of the output value, so we can write it down as x=5.0E+15%.
5. Now we have two simple equations:
1) 31.4848=100%
2) x=5.0E+15%
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:
31.4848/x=100%/5.0E+15%
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 5.0E+15% of 31.4848

31.4848/x=100/5.0E+15
(31.4848/x)*x=(100/5.0E+15)*x       - we multiply both sides of the equation by x
31.4848=2.0E-14*x       - we divide both sides of the equation by (2.0E-14) to get x
31.4848/2.0E-14=x
1.57424E+15=x
x=1.57424E+15

now we have:
5.0E+15% of 31.4848=1.57424E+15
