Toki's tip: every answer in the key comes with a quick “how” you can read out loud together.4th Grade Fractions in 3 Big Ideas
1. Equal fractions
Multiply (or divide) the top and bottom by the same number.
Example: 3/4 = ?/12 → 4 × 3 = 12, so 3 × 3 = 9, and 3/4 = 9/12.
2. Comparing
Give both fractions the same denominator, then compare the tops.
Example: 2/3 and 3/4 → 8/12 and 9/12, so 3/4 is bigger.
3. Same denominator
Add or subtract the tops and keep the bottom. Regroup 1 whole if needed.
Example: 3/8 + 2/8 = 5/8. Not enough to subtract? 4 1/6 = 3 7/6.
