5.0E+19 is what percent of INF - 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 INF 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 INF, so we can write it down as 100%=INF.
4. We know, that x% equals 5.0E+19 of the output value, so we can write it down as x%=5.0E+19.
5. Now we have two simple equations:
1) 100%=INF
2) x%=5.0E+19
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%=INF/5.0E+19
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 5.0E+19 is what percent of INF

100%/x%=INF/5.0E+19
(100/x)*x=(INF/5.0E+19)*x       - we multiply both sides of the equation by x
100=INF*x       - we divide both sides of the equation by (INF) to get x
100/INF=x
0=x
x=0

now we have:
5.0E+19 is 0% of INF
