What is 3.4 percent of 158 - 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 158 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 158 is 100%, so we can write it down as 158=100%.
4. We know, that x is 3.4% of the output value, so we can write it down as x=3.4%.
5. Now we have two simple equations:
1) 158=100%
2) x=3.4%
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:
158/x=100%/3.4%
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 3.4% of 158

158/x=100/3.4
(158/x)*x=(100/3.4)*x       - we multiply both sides of the equation by x
158=29.411764705882*x       - we divide both sides of the equation by (29.411764705882) to get x
158/29.411764705882=x
5.372=x
x=5.372

now we have:
3.4% of 158=5.372
