Question

1/2×2/3 6/7×5/6 9/10×10/11 13/15×15/17

Answer 1

1/2 × 2/3 = 1/3

6/7 × 5/6 = 5/7

9/10 × 10/11 = 9/11

13/15 × 15/17 = 13/17

Answer 2

To calculate each of these expressions, simply multiply the numerators together and multiply the denominators together. Here are the results:

1. (1/2) × (2/3) = (1 × 2) / (2 × 3) = 2 / 6 = 1 / 3

2. (6/7) × (5/6) = (6 × 5) / (7 × 6) = 30 / 42 = 5 / 7

3. (9/10) × (10/11) = (9 × 10) / (10 × 11) = 90 / 110 = 9 / 11

4. (13/15) × (15/17) = (13 × 15) / (15 × 17) = 195 / 255 = 39 / 51

So the results are:

1. 1/3
2. 5/7
3. 9/11
4. 39/51
