Answer 1

15/4 + 27/8 = 57/8 89/8 - 57/8 = 32/8 = 4

Answer 2

Corrine collected 11 1/8 geodes or 89/11 geodes.
Ellen collected 4 5/8 geodes or 27/8 geodes.
Leonda collected 3 3/4 geodes or 15/4 geodes.

Ellen and Leonda collected a total of 27/8 + 15/4 geodes.
They collected 27+30/8 = 57/8 geodes.

Corrine collected 89/11 - 57/8 more geodes.
She collected (89*8 - 57*11)/88 = 85/88 geodes more.
