💡 Understanding "Fraction of Remaining"
Key Concept: When the problem says "³⁄₁₀ of the pages that were left," it means we multiply the fraction by the remaining pages, not the original total.
Complete Calculation:
- Total pages: 400
- Day 1 reading: ⅕ × 400 = 80 pages
- Remaining after Day 1: 400 - 80 = 320 pages
- Day 2 reading: ³⁄₁₀ × 320 = 96 pages
- Still to read: 320 - 96 = 224 pages
Answer: 224 pages
