Answer: 
Step-by-step explanation:
Let be "x" the unknown number.
You know that the 25% of the unknown number "x" is 52.
With this information provided in the exercise, you can set up the following proportion:

Now you must solve for "x". The steps to find its value are:
- Multiply both sides of the equation by "x":

- Multiply both sides by 52:

- Divide both sides by 25:

If you were to plot the x and y intercepts you would see that this will be a vertical ellipses, taller that it is wider. The formula for an ellipse is

. The "a" value is always the bigger value of the a and b. The bigger value, the a, will always go under the variable that is the major axis. The major axis for us is the y axis. a = 3, so 3 squared is 9. b = 1 and 1 squared is 1. So our equation will be

, choice a from above.
