438.5 is what percent of 1700 - 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 1700 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 1700, so we can write it down as 100%=1700.
4. We know, that x% equals 438.5 of the output value, so we can write it down as x%=438.5.
5. Now we have two simple equations:
1) 100%=1700
2) x%=438.5
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%=1700/438.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 438.5 is what percent of 1700

100%/x%=1700/438.5
(100/x)*x=(1700/438.5)*x       - we multiply both sides of the equation by x
100=3.8768529076397*x       - we divide both sides of the equation by (3.8768529076397) to get x
100/3.8768529076397=x
25.794117647059=x
x=25.794117647059

now we have:
438.5 is 25.794117647059% of 1700
