69.64 is what percent of 3.99 - 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 3.99 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 3.99, so we can write it down as 100%=3.99.
4. We know, that x% equals 69.64 of the output value, so we can write it down as x%=69.64.
5. Now we have two simple equations:
1) 100%=3.99
2) x%=69.64
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%=3.99/69.64
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 69.64 is what percent of 3.99

100%/x%=3.99/69.64
(100/x)*x=(3.99/69.64)*x       - we multiply both sides of the equation by x
100=0.057294658242389*x       - we divide both sides of the equation by (0.057294658242389) to get x
100/0.057294658242389=x
1745.3634085213=x
x=1745.3634085213

now we have:
69.64 is 1745.3634085213% of 3.99
