2.3 is what percent of 7.99 - 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 7.99 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 7.99, so we can write it down as 100%=7.99.
4. We know, that x% equals 2.3 of the output value, so we can write it down as x%=2.3.
5. Now we have two simple equations:
1) 100%=7.99
2) x%=2.3
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%=7.99/2.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.3 is what percent of 7.99

100%/x%=7.99/2.3
(100/x)*x=(7.99/2.3)*x       - we multiply both sides of the equation by x
100=3.4739130434783*x       - we divide both sides of the equation by (3.4739130434783) to get x
100/3.4739130434783=x
28.785982478098=x
x=28.785982478098

now we have:
2.3 is 28.785982478098% of 7.99
