780000000 is what percent of 7.442E+15 - 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 7.442E+15 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 7.442E+15, so we can write it down as 100%=7.442E+15.
4. We know, that x% equals 780000000 of the output value, so we can write it down as x%=780000000.
5. Now we have two simple equations:
1) 100%=7.442E+15
2) x%=780000000
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%=7.442E+15/780000000
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 780000000 is what percent of 7.442E+15

100%/x%=7.442E+15/780000000
(100/x)*x=(7.442E+15/780000000)*x       - we multiply both sides of the equation by x
100=9541025.6410256*x       - we divide both sides of the equation by (9541025.6410256) to get x
100/9541025.6410256=x
1.0481053480247E-5=x
x=1.0481053480247E-5

now we have:
780000000 is 1.0481053480247E-5% of 7.442E+15
