49.4 is what percent of 100 - 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 100 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 100, so we can write it down as 100%=100.
4. We know, that x% equals 49.4 of the output value, so we can write it down as x%=49.4.
5. Now we have two simple equations:
1) 100%=100
2) x%=49.4
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%=100/49.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 49.4 is what percent of 100

100%/x%=100/49.4
(100/x)*x=(100/49.4)*x       - we multiply both sides of the equation by x
100=2.0242914979757*x       - we divide both sides of the equation by (2.0242914979757) to get x
100/2.0242914979757=x
49.4=x
x=49.4

now we have:
49.4 is 49.4% of 100
