What is 17.5 percent of 443.8 - 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 443.8 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 443.8 is 100%, so we can write it down as 443.8=100%.
4. We know, that x is 17.5% of the output value, so we can write it down as x=17.5%.
5. Now we have two simple equations:
1) 443.8=100%
2) x=17.5%
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:
443.8/x=100%/17.5%
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 17.5% of 443.8

443.8/x=100/17.5
(443.8/x)*x=(100/17.5)*x       - we multiply both sides of the equation by x
443.8=5.7142857142857*x       - we divide both sides of the equation by (5.7142857142857) to get x
443.8/5.7142857142857=x
77.665=x
x=77.665

now we have:
17.5% of 443.8=77.665
