Answer 3

Let's simplify the given expressions:

1. (2/5) * (1/3) * (10/9) = (2 * 1 * 10) / (5 * 3 * 9) = 20 / 135 = 4 / 27

2. (2/3) * (5/2) * (3/5) * (1/2) = (2 * 5 * 3 * 1) / (3 * 2 * 5 * 2) = 30 / 60 = 1/2

3. (1/10) * (6/14) = (1 * 6) / (10 * 14) = 6 / 140 = 3 / 70

4. (3/5) * (10/3) * (2/3) * (1/25) = (3 * 10 * 2 * 1) / (5 * 3 * 3 * 25) = 60 / 1125 = 4 / 75

5. (6/5) * (25/20) * (2/36) = (6 * 25 * 2) / (5 * 20 * 36) = 300 / 3600 = 1 / 12

6. (5/4) * (2/3) * (6/10) = (5 * 2 * 6) / (4 * 3 * 10) = 60 / 120 = 1/2

So the simplified expressions are:

1. 4/27
2. 1/2
3. 3/70
4. 4/75
5. 1/12
6. 1/2
