Answer 2

Let's calculate the given expressions:

1. 0.125 * 5: This is a simple multiplication of decimal numbers: 0.125 * 5 = 0.625

2. (1/3) * (3/4): To multiply fractions, multiply the numerators together and multiply the denominators together: (1/3) * (3/4) = (1 * 3) / (3 * 4) = 3/12 = 1/4

3. (4/7) * (21/32) * (8/9): Multiply the numerators together and multiply the denominators together: (4/7) * (21/32) * (8/9) = (4 * 21 * 8) / (7 * 32 * 9) = 672/2016 = 1/3

4. (1 5/27) * (3/4^2) * 6: First, simplify the mixed number (1 5/27) to an improper fraction: 1 5/27 = (1 * 27 + 5) / 27 = 32/27

   Next, calculate (3/4^2) which means 3 divided by 4 squared: (3/4^2) = (3/16)

   Finally, multiply all the fractions together and then multiply by 6: (32/27) * (3/16) * 6 = (32 * 3 * 6) / (27 * 16) = 576/432 = 4/3 = 1 1/3

5. 0.375 * (9 1/3) * (2/7): First, convert the mixed number (9 1/3) to an improper fraction: 9 1/3 = (9 * 3 + 1) / 3 = 28/3

   Then, multiply all the numbers together: 0.375 * (28/3) * (2/7) = (0.375 * 28 * 2) / (3 * 7) = 21/4 = 5.25

Therefore, the results are:

1. 0.125 * 5 = 0.625
2. (1/3) * (3/4) = 1/4
3. (4/7) * (21/32) * (8/9) = 1/3
4. (1 5/27) * (3/4^2) * 6 = 1 1/3
5. 0.375 * (9 1/3) * (2/7) = 5.25
