239.99 is what percent of 339.99 - 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 339.99 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 339.99, so we can write it down as 100%=339.99.
4. We know, that x% equals 239.99 of the output value, so we can write it down as x%=239.99.
5. Now we have two simple equations:
1) 100%=339.99
2) x%=239.99
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%=339.99/239.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 239.99 is what percent of 339.99

100%/x%=339.99/239.99
(100/x)*x=(339.99/239.99)*x       - we multiply both sides of the equation by x
100=1.4166840285012*x       - we divide both sides of the equation by (1.4166840285012) to get x
100/1.4166840285012=x
70.587370216771=x
x=70.587370216771

now we have:
