What is 2.45 percent of 173 - 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 173 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 173 is 100%, so we can write it down as 173=100%.
4. We know, that x is 2.45% of the output value, so we can write it down as x=2.45%.
5. Now we have two simple equations:
1) 173=100%
2) x=2.45%
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:
173/x=100%/2.45%
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 2.45% of 173

173/x=100/2.45
(173/x)*x=(100/2.45)*x       - we multiply both sides of the equation by x
173=40.816326530612*x       - we divide both sides of the equation by (40.816326530612) to get x
173/40.816326530612=x
4.2385=x
x=4.2385

now we have:
2.45% of 173=4.2385
