What is 69.9999 percent of 1230 - 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 1230 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 1230 is 100%, so we can write it down as 1230=100%.
4. We know, that x is 69.9999% of the output value, so we can write it down as x=69.9999%.
5. Now we have two simple equations:
1) 1230=100%
2) x=69.9999%
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:
1230/x=100%/69.9999%
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 69.9999% of 1230

1230/x=100/69.9999
(1230/x)*x=(100/69.9999)*x       - we multiply both sides of the equation by x
1230=1.4285734693907*x       - we divide both sides of the equation by (1.4285734693907) to get x
1230/1.4285734693907=x
860.99877=x
x=860.99877

now we have:
69.9999% of 1230=860.99877
