99.7 is what percent of 250 - 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 250 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 250, so we can write it down as 100%=250.
4. We know, that x% equals 99.7 of the output value, so we can write it down as x%=99.7.
5. Now we have two simple equations:
1) 100%=250
2) x%=99.7
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%=250/99.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 99.7 is what percent of 250

100%/x%=250/99.7
(100/x)*x=(250/99.7)*x       - we multiply both sides of the equation by x
100=2.5075225677031*x       - we divide both sides of the equation by (2.5075225677031) to get x
100/2.5075225677031=x
39.88=x
x=39.88

now we have:
99.7 is 39.88% of 250
