4900000 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 4900000 of the output value, so we can write it down as x%=4900000.
5. Now we have two simple equations:
1) 100%=7
2) x%=4900000
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%=7/4900000
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4900000 is what percent of 7

100%/x%=7/4900000
(100/x)*x=(7/4900000)*x       - we multiply both sides of the equation by x
100=1.4285714285714E-6*x       - we divide both sides of the equation by (1.4285714285714E-6) to get x
100/1.4285714285714E-6=x
70000000=x
x=70000000

now we have:
4900000 is 70000000% of 7
