210.5 is what percent of 1254 - 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 1254 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 1254, so we can write it down as 100%=1254.
4. We know, that x% equals 210.5 of the output value, so we can write it down as x%=210.5.
5. Now we have two simple equations:
1) 100%=1254
2) x%=210.5
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%=1254/210.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 210.5 is what percent of 1254

100%/x%=1254/210.5
(100/x)*x=(1254/210.5)*x       - we multiply both sides of the equation by x
100=5.9572446555819*x       - we divide both sides of the equation by (5.9572446555819) to get x
100/5.9572446555819=x
16.786283891547=x
x=16.786283891547

now we have:
210.5 is 16.786283891547% of 1254
