178.24 is what percent of 400 - 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 400 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 100% equals 400, so we can write it down as 100%=400.
4. We know, that x% equals 178.24 of the output value, so we can write it down as x%=178.24.
5. Now we have two simple equations:
1) 100%=400
2) x%=178.24
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:
100%/x%=400/178.24
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 178.24 is what percent of 400

100%/x%=400/178.24
(100/x)*x=(400/178.24)*x       - we multiply both sides of the equation by x
100=2.2441651705566*x       - we divide both sides of the equation by (2.2441651705566) to get x
100/2.2441651705566=x
44.56=x
x=44.56

now we have:
178.24 is 44.56% of 400
