3.99 is what percent of 10.99 - 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 10.99 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 10.99, so we can write it down as 100%=10.99.
4. We know, that x% equals 3.99 of the output value, so we can write it down as x%=3.99.
5. Now we have two simple equations:
1) 100%=10.99
2) x%=3.99
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%=10.99/3.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.99 is what percent of 10.99

100%/x%=10.99/3.99
(100/x)*x=(10.99/3.99)*x       - we multiply both sides of the equation by x
100=2.7543859649123*x       - we divide both sides of the equation by (2.7543859649123) to get x
100/2.7543859649123=x
36.305732484076=x
x=36.305732484076

now we have:
3.99 is 36.305732484076% of 10.99
