Lizzy: Simone ate 1/2 of an apple each day for 16 days. Lauri ate 1/3 of an apple each day for 15 days. How many apples did the two girls eat altogether?.
Me: Hmmm, let me think. I think this is the detailed solution:
Simone = (1 / 2) * 16 = 8. Lauri = (1 / 3) * 15 = 5. 8 + 5 = 13. Together they ate 13 apples. Final answer: 13.
