455000 is what percent of 7.5E+14 - 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 7.5E+14 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% equals 7.5E+14, so we can write it down as 100%=7.5E+14.
4. We know, that x% equals 455000 of the output value, so we can write it down as x%=455000.
5. Now we have two simple equations:
1) 100%=7.5E+14
2) x%=455000
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%=7.5E+14/455000
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 455000 is what percent of 7.5E+14

100%/x%=7.5E+14/455000
(100/x)*x=(7.5E+14/455000)*x       - we multiply both sides of the equation by x
100=1648351648.3516*x       - we divide both sides of the equation by (1648351648.3516) to get x
100/1648351648.3516=x
6.0666666666667E-8=x
x=6.0666666666667E-8

now we have:
455000 is 6.0666666666667E-8% of 7.5E+14
