Multiplying Mixed Numbers
The key: Convert both to improper fractions first, then multiply straight across!
1
2½ × 1⅓ = 5/2 × 4/32
5 × 4 = 203
2 × 3 = 64
20/6 = 10/3 = 3⅓Dividing Mixed Numbers
Use KCF: Keep, Change, Flip - Keep the first, Change ÷ to ×, Flip the second!
1
3½ ÷ 1¼ = 7/2 ÷ 5/42
7/2 × 4/53
28/10 = 14/54
14/5 = 2⅘💡Pro Tip: Cross-Cancel First
Before multiplying, look for common factors you can cancel between any numerator and any denominator. This makes the math easier and gives you a simpler answer!
⚠️ Don't Forget
- Always convert to improper fractions before multiplying/dividing
- For division, flip only the SECOND fraction
- Simplify your final answer and convert back to mixed if needed
