4 is what percent of 993 - 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 993 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 993, so we can write it down as 100%=993.
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%=993
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%=993/4
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 993

100%/x%=993/4
(100/x)*x=(993/4)*x       - we multiply both sides of the equation by x
100=248.25*x       - we divide both sides of the equation by (248.25) to get x
100/248.25=x
0.40281973816717=x
x=0.40281973816717

now we have:
4 is 0.40281973816717% of 993
