What is 47.2 percent of 438000000 - 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 438000000 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 438000000 is 100%, so we can write it down as 438000000=100%.
4. We know, that x is 47.2% of the output value, so we can write it down as x=47.2%.
5. Now we have two simple equations:
1) 438000000=100%
2) x=47.2%
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:
438000000/x=100%/47.2%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 47.2% of 438000000

438000000/x=100/47.2
(438000000/x)*x=(100/47.2)*x       - we multiply both sides of the equation by x
438000000=2.1186440677966*x       - we divide both sides of the equation by (2.1186440677966) to get x
438000000/2.1186440677966=x
206736000=x
x=206736000

now we have:
47.2% of 438000000=206736000
