What is 4.3E-7 percent of 230000000 - 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 230000000 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 230000000 is 100%, so we can write it down as 230000000=100%.
4. We know, that x is 4.3E-7% of the output value, so we can write it down as x=4.3E-7%.
5. Now we have two simple equations:
1) 230000000=100%
2) x=4.3E-7%
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:
230000000/x=100%/4.3E-7%
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 4.3E-7% of 230000000

230000000/x=100/4.3E-7
(230000000/x)*x=(100/4.3E-7)*x       - we multiply both sides of the equation by x
230000000=232558139.53488*x       - we divide both sides of the equation by (232558139.53488) to get x
230000000/232558139.53488=x
0.989=x
x=0.989

now we have:
4.3E-7% of 230000000=0.989
