123 is what percent of 1.2312312312312E+71 - 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 1.2312312312312E+71 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 1.2312312312312E+71, so we can write it down as 100%=1.2312312312312E+71.
4. We know, that x% equals 123 of the output value, so we can write it down as x%=123.
5. Now we have two simple equations:
1) 100%=1.2312312312312E+71
2) x%=123
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%=1.2312312312312E+71/123
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 123 is what percent of 1.2312312312312E+71

100%/x%=1.2312312312312E+71/123
(100/x)*x=(1.2312312312312E+71/123)*x       - we multiply both sides of the equation by x
100=1.001001001001E+69*x       - we divide both sides of the equation by (1.001001001001E+69) to get x
100/1.001001001001E+69=x
9.99E-68=x
x=9.99E-68

now we have:
123 is 9.99E-68% of 1.2312312312312E+71
