2.83 is what percent of 21.99 - 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 21.99 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 21.99, so we can write it down as 100%=21.99.
4. We know, that x% equals 2.83 of the output value, so we can write it down as x%=2.83.
5. Now we have two simple equations:
1) 100%=21.99
2) x%=2.83
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%=21.99/2.83
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.83 is what percent of 21.99

100%/x%=21.99/2.83
(100/x)*x=(21.99/2.83)*x       - we multiply both sides of the equation by x
100=7.7703180212014*x       - we divide both sides of the equation by (7.7703180212014) to get x
100/7.7703180212014=x
12.869486130059=x
x=12.869486130059

now we have:
2.83 is 12.869486130059% of 21.99
