17.9 is what percent of 44.75 - 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 44.75 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 44.75, so we can write it down as 100%=44.75.
4. We know, that x% equals 17.9 of the output value, so we can write it down as x%=17.9.
5. Now we have two simple equations:
1) 100%=44.75
2) x%=17.9
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%=44.75/17.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.9 is what percent of 44.75

100%/x%=44.75/17.9
(100/x)*x=(44.75/17.9)*x       - we multiply both sides of the equation by x
100=2.5*x       - we divide both sides of the equation by (2.5) to get x
100/2.5=x
40=x
x=40

now we have:
17.9 is 40% of 44.75
