What is 33.33 percent of 438 - 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 438 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 438 is 100%, so we can write it down as 438=100%.
4. We know, that x is 33.33% of the output value, so we can write it down as x=33.33%.
5. Now we have two simple equations:
1) 438=100%
2) x=33.33%
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:
438/x=100%/33.33%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 33.33% of 438

438/x=100/33.33
(438/x)*x=(100/33.33)*x       - we multiply both sides of the equation by x
438=3.000300030003*x       - we divide both sides of the equation by (3.000300030003) to get x
438/3.000300030003=x
145.9854=x
x=145.9854

now we have:
33.33% of 438=145.9854
