1500000 is what percent of 4 - 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 4 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 4, so we can write it down as 100%=4.
4. We know, that x% equals 1500000 of the output value, so we can write it down as x%=1500000.
5. Now we have two simple equations:
1) 100%=4
2) x%=1500000
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%=4/1500000
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1500000 is what percent of 4

100%/x%=4/1500000
(100/x)*x=(4/1500000)*x       - we multiply both sides of the equation by x
100=2.6666666666667E-6*x       - we divide both sides of the equation by (2.6666666666667E-6) to get x
100/2.6666666666667E-6=x
37500000=x
x=37500000

now we have:
1500000 is 37500000% of 4
