Answer 2

To solve the expression, let's calculate each part step by step:

1. 3/4 * 1: Multiplying 3/4 by 1 gives us: 3/4.

2. 1 1/15 + 1 1/15: Adding the whole numbers separately and the fractions separately, we have: 1 + 1 = 2 (whole numbers) 1/15 + 1/15 = 2/15 (fractions) Therefore, the result is 2 2/15.

3. 2 1/15 * 2: Multiplying 2 by 2 gives us 4, and multiplying 1/15 by 2 gives us 2/15. Combining the whole number and fraction parts, we have: 4 + 2/15 = 4 2/15.

4. 1 1/2 - 1 3/8: Subtracting the whole numbers separately and the fractions separately, we have: 1 - 1 = 0 (whole numbers) 1/2 - 3/8 = 4/8 - 3/8 = 1/8 (fractions) Therefore, the result is 0 1/8.

5. 1 1/15 * 1 1/15: Multiplying the whole numbers separately and the fractions separately, we have: 1 * 1 = 1 (whole numbers) 1/15 * 1/15 = 1/225 (fractions) Therefore, the result is 1 1/225.

In summary, the expression evaluates to: 3/4 * 1 + 1 1/15 + 1 1/15 * 2 - 1 3/8 * 1 1/15 = 3/4 + 2 2/15 + 4 2/15 - 0 1/8 + 1 1/225.
