What is 17.3 percent of 399.8 - 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 399.8 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 399.8 is 100%, so we can write it down as 399.8=100%.
4. We know, that x is 17.3% of the output value, so we can write it down as x=17.3%.
5. Now we have two simple equations:
1) 399.8=100%
2) x=17.3%
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:
399.8/x=100%/17.3%
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 17.3% of 399.8

399.8/x=100/17.3
(399.8/x)*x=(100/17.3)*x       - we multiply both sides of the equation by x
399.8=5.7803468208092*x       - we divide both sides of the equation by (5.7803468208092) to get x
399.8/5.7803468208092=x
69.1654=x
x=69.1654

now we have:
17.3% of 399.8=69.1654
