Dividing Fractions
Math assignment · Roosevelt SEIS · Step-by-step support
Remember: Keep, Change, Flip
To divide fractions: Keep the first fraction, Change ÷ to ×, Flip the second fraction (use its reciprocal). Then multiply.
1. Keep
2. Change ÷ → ×
3. Flip
4. Multiply
Example with arrows:
12
÷
14
→
Keep
12
×
41
(flip ¼ → ⁴⁄₁)
↑ Multiply: top × top = 1×4 = 4 bottom × bottom = 2×1 = 2 → Answer: 4⁄2 = 2
