1. 7/8
Keep the first fraction, flip the second: 7/4. 1/2 × 7/4 = 7/8. Simplify → 7/8
2. 7/2
Keep the first fraction, flip the second: 4/1. 7/8 × 4/1 = 28/8. Simplify → 7/2
3. 2
Keep the first fraction, flip the second: 2/1. 2/2 × 2/1 = 4/2. Simplify → 2
4. 9/4
Keep the first fraction, flip the second: 9/2. 4/8 × 9/2 = 36/16. Simplify → 9/4
5. 1/3
Keep the first fraction, flip the second: 3/1. 1/9 × 3/1 = 3/9. Simplify → 1/3
6. 54/7
Keep the first fraction, flip the second: 9/1. 6/7 × 9/1 = 54/7. Simplify → 54/7
7. 21/8
Keep the first fraction, flip the second: 7/2. 3/4 × 7/2 = 21/8. Simplify → 21/8
8. 1/3
Keep the first fraction, flip the second: 6/6. 1/3 × 6/6 = 6/18. Simplify → 1/3
9. 6/5
Keep the first fraction, flip the second: 8/5. 3/4 × 8/5 = 24/20. Simplify → 6/5
10. 9/4
Keep the first fraction, flip the second: 3/1. 3/4 × 3/1 = 9/4. Simplify → 9/4
