4 is what percent of 121.05 - 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 121.05 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 121.05, so we can write it down as 100%=121.05.
4. We know, that x% equals 4 of the output value, so we can write it down as x%=4.
5. Now we have two simple equations:
1) 100%=121.05
2) x%=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%=121.05/4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4 is what percent of 121.05

100%/x%=121.05/4
(100/x)*x=(121.05/4)*x       - we multiply both sides of the equation by x
100=30.2625*x       - we divide both sides of the equation by (30.2625) to get x
100/30.2625=x
3.304419661297=x
x=3.304419661297

now we have:
4 is 3.304419661297% of 121.05
