2.71 is what percent of 84 - 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 84 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 84, so we can write it down as 100%=84.
4. We know, that x% equals 2.71 of the output value, so we can write it down as x%=2.71.
5. Now we have two simple equations:
1) 100%=84
2) x%=2.71
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%=84/2.71
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.71 is what percent of 84

100%/x%=84/2.71
(100/x)*x=(84/2.71)*x       - we multiply both sides of the equation by x
100=30.9963099631*x       - we divide both sides of the equation by (30.9963099631) to get x
100/30.9963099631=x
3.2261904761905=x
x=3.2261904761905

now we have:
2.71 is 3.2261904761905% of 84
