Answer:
5/12
Step-by-step explanation:
2 2/5 = 12/5 so its reciprocal is 5/12
Reciprocals are fractions that are basically "flipped". You flip the denominator to the numerator and vice versa.

+

= 1
This is because the standard form of an ellipse is

+

= 1
where a is the vertex and b is the co-vertex. So when we stick their respective x and y values in and then square them, you're left with the answer above.
