2.76 is what percent of 7 - 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 7 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 7, so we can write it down as 100%=7.
4. We know, that x% equals 2.76 of the output value, so we can write it down as x%=2.76.
5. Now we have two simple equations:
1) 100%=7
2) x%=2.76
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%=7/2.76
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.76 is what percent of 7

100%/x%=7/2.76
(100/x)*x=(7/2.76)*x       - we multiply both sides of the equation by x
100=2.536231884058*x       - we divide both sides of the equation by (2.536231884058) to get x
100/2.536231884058=x
39.428571428571=x
x=39.428571428571

now we have:
2.76 is 39.428571428571% of 7
