70 is what percent of 318000000 - 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 318000000 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 318000000, so we can write it down as 100%=318000000.
4. We know, that x% equals 70 of the output value, so we can write it down as x%=70.
5. Now we have two simple equations:
1) 100%=318000000
2) x%=70
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%=318000000/70
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 70 is what percent of 318000000

100%/x%=318000000/70
(100/x)*x=(318000000/70)*x       - we multiply both sides of the equation by x
100=4542857.1428571*x       - we divide both sides of the equation by (4542857.1428571) to get x
100/4542857.1428571=x
2.2012578616352E-5=x
x=2.2012578616352E-5

now we have:
70 is 2.2012578616352E-5% of 318000000
