2.8 is what percent of 9.4 - 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 9.4 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 9.4, so we can write it down as 100%=9.4.
4. We know, that x% equals 2.8 of the output value, so we can write it down as x%=2.8.
5. Now we have two simple equations:
1) 100%=9.4
2) x%=2.8
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%=9.4/2.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.8 is what percent of 9.4

100%/x%=9.4/2.8
(100/x)*x=(9.4/2.8)*x       - we multiply both sides of the equation by x
100=3.3571428571429*x       - we divide both sides of the equation by (3.3571428571429) to get x
100/3.3571428571429=x
29.787234042553=x
x=29.787234042553

now we have:
2.8 is 29.787234042553% of 9.4
