1400000 is what percent of 7 - 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 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, so we can write it down as 100%=7.
4. We know, that x% equals 1400000 of the output value, so we can write it down as x%=1400000.
5. Now we have two simple equations:
1) 100%=7
2) x%=1400000
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%=7/1400000
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1400000 is what percent of 7

100%/x%=7/1400000
(100/x)*x=(7/1400000)*x       - we multiply both sides of the equation by x
100=5.0E-6*x       - we divide both sides of the equation by (5.0E-6) to get x
100/5.0E-6=x
20000000=x
x=20000000

now we have:
1400000 is 20000000% of 7
