Answer 3

Let's solve the expression step by step:

Step 1: Evaluate the terms inside the parentheses first. (3 * 5/21 - 2 * 9/14) * 1 * 13/15 / (1 * 1/6 + 1 * 1/3)

Step 2: Simplify the terms inside the parentheses.

3 * 5/21 = 15/21 2 * 9/14 = 18/14

So, (15/21 - 18/14) * 1 * 13/15 / (1 * 1/6 + 1 * 1/3)

Step 3: Convert fractions to a common denominator.

The common denominator for 21 and 14 is 42.

(15/21 - 18/14) * 1 * 13/15 / (1 * 1/6 + 1 * 1/3)

(30/42 - 27/42) * 1 * 13/15 / (1 * 7/42 + 1 * 14/42)

Step 4: Simplify the fractions.

(3/42) * 1 * 13/15 / (21/42 + 28/42)

Step 5: Perform the additions inside the parentheses.

(3/42) * 1 * 13/15 / (49/42)

Step 6: Invert the denominator and multiply.

(3/42) * 1 * 13/15 * 42/49

Step 7: Simplify the expression.

(1/14) * 13/15 * 6/7

Step 8: Multiply the fractions.

(13/210) * 6/7

Step 9: Simplify the result.

13/35 ≈ 0.3714285714

So, the final result of the expression is approximately 0.3714.
