218.75 is what percent of 17500 - 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 17500 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 17500, so we can write it down as 100%=17500.
4. We know, that x% equals 218.75 of the output value, so we can write it down as x%=218.75.
5. Now we have two simple equations:
1) 100%=17500
2) x%=218.75
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%=17500/218.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 218.75 is what percent of 17500

100%/x%=17500/218.75
(100/x)*x=(17500/218.75)*x       - we multiply both sides of the equation by x
100=80*x       - we divide both sides of the equation by (80) to get x
100/80=x
1.25=x
x=1.25

now we have:
218.75 is 1.25% of 17500
