Answer:
27/36, or simplified, 3/4
Explanation:
You add the number of elements named after woman scientists to the number of elements named after places: 2+25 = 27.
That is 27 out of the 36, so you put 27 over 36 in a fraction.

To simplify, divide both 27 and 36 by 9.
27 ÷ 9 = 3;
36 ÷ 9 =4;
Simplified answer is 3/4
