Answer 2

To solve the given expression, let's take it step by step:

Step 1: Simplify the expressions within parentheses and perform the division.

(1/2 - 1/7 - 1/4) : (2 5/14 - 1 8/21 - 1/3) + (5.3 * 0.7 + 1.29) : (7.3 - 1.44 / 0.8)

Step 2: Perform the operations inside the parentheses first.

(1/2 - 1/7 - 1/4) : (2 5/14 - 1 8/21 - 1/3) + (3.71) : (7.3 - 1.8)

Step 3: Convert the mixed numbers to improper fractions.

(1/2 - 1/7 - 1/4) : (33/14 - 47/21 - 1/3) + (3.71) : (7.3 - 1.8)

Step 4: Find the common denominator for the fractions and perform the subtraction.

(21/42 - 6/42 - 21/42) + (3.71) : (7.3 - 1.8)

Step 5: Combine like terms in the first expression.

-6/42 + (3.71) : (7.3 - 1.8)

Step 6: Perform the operations inside the parentheses first.

-6/42 + (3.71) : (5.5)

Step 7: Divide the value on the right side.

-6/42 + 3.71 / 5.5

Step 8: Perform the division.

-6/42 + 0.67454545...

Step 9: Convert the decimal to a fraction.

-6/42 + 0.67454545... ≈ -6/42 + 15/22

Step 10: Find the common denominator for the fractions and perform the addition.

-3/21 + 15/22

Step 11: Convert the fractions to a common denominator.

-6/42 + 15/42

Step 12: Perform the addition.

9/42

Step 13: Simplify the fraction.

9/42 = 3/14

So, the final answer is 3/14.
