What is 3 percent of 153 - 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 153 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 153 is 100%, so we can write it down as 153=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) 153=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:
153/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 153

153/x=100/3
(153/x)*x=(100/3)*x       - we multiply both sides of the equation by x
153=33.333333333333*x       - we divide both sides of the equation by (33.333333333333) to get x
153/33.333333333333=x
4.59=x
x=4.59

now we have:
3% of 153=4.59
