Question

Part 1: Two custodians are painting the hallway in the school, starting

at opposite ends at 10:00 a.m. By noon, if Jon has painted 1/5 of the
hallway and Dan has painted 25% of the hallway, who has painted the
most?
25
Part 2: What percentage of the job needs to be completed after lunch

Answer 1

Answer: Part 1: Dan, Part 2: 55%

Explanation:

1. By noon, Jon has painted 1/5 (or 20%) of the hallway and Dan has painted 25% of the hallway. Therefore, Dan has painted more of the hallway than Jon.

2. In total, the two have painted 45% (20% + 25% = 45%) of the hallway by lunchtime. Therefore, 55% (100% - 45% = 55%) needs to be painted after lunch.
