70 is what percent of 4000000 - 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 4000000 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 4000000, so we can write it down as 100%=4000000.
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%=4000000
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%=4000000/70
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 4000000

100%/x%=4000000/70
(100/x)*x=(4000000/70)*x       - we multiply both sides of the equation by x
100=57142.857142857*x       - we divide both sides of the equation by (57142.857142857) to get x
100/57142.857142857=x
0.00175=x
x=0.00175

now we have:
70 is 0.00175% of 4000000
