Question

which example best matches the division equation $50 \div 10 = 5$?
justin has 50 puzzle cards and 10 rooms throughout the mansion to hide them in. he can hide 5 cards in each room.
justin has 5 puzzle cards and 10 rooms throughout the mansion to hide them in. he can hide 50 cards in each room.
all of these are correct.
justin has 10 puzzle cards and 50 rooms throughout the mansion to hide them in. he can hide 5 cards in each room.

Explanation:

We analyze each option against $50 \div 10 = 5$:

1. First option: Total cards = 50, number of rooms = 10, cards per room = 5. This matches dividing total cards by rooms to get cards per room ($50 \div 10 = 5$).
2. Second option: Total cards = 5, rooms =10, claims 50 per room. This contradicts the equation.
3. Fourth option: Total cards =10, rooms=50, claims 5 per room. This does not match the equation.

Answer:

A. Justin has 50 puzzle cards and 10 rooms throughout the mansion to hide them in. He can hide 5 cards in each room.
