2.79 is what percent of 12.96 - 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 12.96 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 12.96, so we can write it down as 100%=12.96.
4. We know, that x% equals 2.79 of the output value, so we can write it down as x%=2.79.
5. Now we have two simple equations:
1) 100%=12.96
2) x%=2.79
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%=12.96/2.79
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.79 is what percent of 12.96

100%/x%=12.96/2.79
(100/x)*x=(12.96/2.79)*x       - we multiply both sides of the equation by x
100=4.6451612903226*x       - we divide both sides of the equation by (4.6451612903226) to get x
100/4.6451612903226=x
21.527777777778=x
x=21.527777777778

now we have:
2.79 is 21.527777777778% of 12.96
