3.99 is what percent of 178.95 - 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 178.95 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 178.95, so we can write it down as 100%=178.95.
4. We know, that x% equals 3.99 of the output value, so we can write it down as x%=3.99.
5. Now we have two simple equations:
1) 100%=178.95
2) x%=3.99
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%=178.95/3.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.99 is what percent of 178.95

100%/x%=178.95/3.99
(100/x)*x=(178.95/3.99)*x       - we multiply both sides of the equation by x
100=44.84962406015*x       - we divide both sides of the equation by (44.84962406015) to get x
100/44.84962406015=x
2.2296730930427=x
x=2.2296730930427

now we have:
3.99 is 2.2296730930427% of 178.95
