43.8 is what percent of 17.9 - 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 17.9 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 17.9, so we can write it down as 100%=17.9.
4. We know, that x% equals 43.8 of the output value, so we can write it down as x%=43.8.
5. Now we have two simple equations:
1) 100%=17.9
2) x%=43.8
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%=17.9/43.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 43.8 is what percent of 17.9

100%/x%=17.9/43.8
(100/x)*x=(17.9/43.8)*x       - we multiply both sides of the equation by x
100=0.40867579908676*x       - we divide both sides of the equation by (0.40867579908676) to get x
100/0.40867579908676=x
244.69273743017=x
x=244.69273743017

now we have:
43.8 is 244.69273743017% of 17.9
