153 is what percent of 1.0E+60 - 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 1.0E+60 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 1.0E+60, so we can write it down as 100%=1.0E+60.
4. We know, that x% equals 153 of the output value, so we can write it down as x%=153.
5. Now we have two simple equations:
1) 100%=1.0E+60
2) x%=153
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%=1.0E+60/153
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 153 is what percent of 1.0E+60

100%/x%=1.0E+60/153
(100/x)*x=(1.0E+60/153)*x       - we multiply both sides of the equation by x
100=6.5359477124183E+57*x       - we divide both sides of the equation by (6.5359477124183E+57) to get x
100/6.5359477124183E+57=x
1.53E-56=x
x=1.53E-56

now we have:
153 is 1.53E-56% of 1.0E+60
