What is 3000000000 percent of 0.7 - 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 0.7 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 0.7 is 100%, so we can write it down as 0.7=100%.
4. We know, that x is 3000000000% of the output value, so we can write it down as x=3000000000%.
5. Now we have two simple equations:
1) 0.7=100%
2) x=3000000000%
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:
0.7/x=100%/3000000000%
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 3000000000% of 0.7

0.7/x=100/3000000000
(0.7/x)*x=(100/3000000000)*x       - we multiply both sides of the equation by x
0.7=3.3333333333333E-8*x       - we divide both sides of the equation by (3.3333333333333E-8) to get x
0.7/3.3333333333333E-8=x
21000000=x
x=21000000

now we have:
3000000000% of 0.7=21000000
