173.9 is what percent of 174.2 - 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 174.2 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 174.2, so we can write it down as 100%=174.2.
4. We know, that x% equals 173.9 of the output value, so we can write it down as x%=173.9.
5. Now we have two simple equations:
1) 100%=174.2
2) x%=173.9
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%=174.2/173.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 173.9 is what percent of 174.2

100%/x%=174.2/173.9
(100/x)*x=(174.2/173.9)*x       - we multiply both sides of the equation by x
100=1.0017251293847*x       - we divide both sides of the equation by (1.0017251293847) to get x
100/1.0017251293847=x
99.827784156142=x
x=99.827784156142

now we have:
173.9 is 99.827784156142% of 174.2
