43.75 is what percent of 81.25 - 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 81.25 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 81.25, so we can write it down as 100%=81.25.
4. We know, that x% equals 43.75 of the output value, so we can write it down as x%=43.75.
5. Now we have two simple equations:
1) 100%=81.25
2) x%=43.75
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%=81.25/43.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 43.75 is what percent of 81.25

100%/x%=81.25/43.75
(100/x)*x=(81.25/43.75)*x       - we multiply both sides of the equation by x
100=1.8571428571429*x       - we divide both sides of the equation by (1.8571428571429) to get x
100/1.8571428571429=x
53.846153846154=x
x=53.846153846154

now we have:
43.75 is 53.846153846154% of 81.25
