What is 3 percent of 158.99 - 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 158.99 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 158.99 is 100%, so we can write it down as 158.99=100%.
4. We know, that x is 3% of the output value, so we can write it down as x=3%.
5. Now we have two simple equations:
1) 158.99=100%
2) x=3%
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:
158.99/x=100%/3%
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% of 158.99

158.99/x=100/3
(158.99/x)*x=(100/3)*x       - we multiply both sides of the equation by x
158.99=33.333333333333*x       - we divide both sides of the equation by (33.333333333333) to get x
158.99/33.333333333333=x
4.7697=x
x=4.7697

now we have:
3% of 158.99=4.7697
