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

7. Solution for 4 is what percent of 43.75

100%/x%=43.75/4
(100/x)*x=(43.75/4)*x       - we multiply both sides of the equation by x
100=10.9375*x       - we divide both sides of the equation by (10.9375) to get x
100/10.9375=x
9.1428571428571=x
x=9.1428571428571

now we have:
4 is 9.1428571428571% of 43.75
