251.9 is what percent of 330 - 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 330 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 330, so we can write it down as 100%=330.
4. We know, that x% equals 251.9 of the output value, so we can write it down as x%=251.9.
5. Now we have two simple equations:
1) 100%=330
2) x%=251.9
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%=330/251.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 251.9 is what percent of 330

100%/x%=330/251.9
(100/x)*x=(330/251.9)*x       - we multiply both sides of the equation by x
100=1.3100436681223*x       - we divide both sides of the equation by (1.3100436681223) to get x
100/1.3100436681223=x
76.333333333333=x
x=76.333333333333

now we have:
251.9 is 76.333333333333% of 330
