Answer:
3/4
Step-by-step explanation:
The number of barrels on Thursday is the product of the number of barrels on Wednesday and the ratio of barrels Thursday/Wednesday.
... (Wed barrels) × (Thu barrels)/(Wed barrels) = (Thu barrels)
... 9/10 × 5/6 = (9×5)/(10×6) = 45/60
... = (3×15)/(4×15) = 3/4 . . . . barrels picked on Thursday
