43.45 is what percent of 50 - 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 50 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 50, so we can write it down as 100%=50.
4. We know, that x% equals 43.45 of the output value, so we can write it down as x%=43.45.
5. Now we have two simple equations:
1) 100%=50
2) x%=43.45
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%=50/43.45
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 43.45 is what percent of 50

100%/x%=50/43.45
(100/x)*x=(50/43.45)*x       - we multiply both sides of the equation by x
100=1.150747986191*x       - we divide both sides of the equation by (1.150747986191) to get x
100/1.150747986191=x
86.9=x
x=86.9

now we have:
43.45 is 86.9% of 50
