Answer 2

Let's simplify the given expression step by step:

Step 1: Perform the operations inside the parentheses.

(2 - 1 7/12) : (3/8 - 1/6) • 3 1/44) (7/10 - 2/5) • (1/4 + 5/6) : 6 1/2

= (1 5/12) : (1/24) • 3 1/44) (7/10 - 2/5) • (3/4) : 6 1/2

Step 2: Convert the mixed numbers to improper fractions.

= (17/12) : (1/24) • 3 1/44) (7/10 - 2/5) • (3/4) : 13/2

Step 3: Invert the divisor and multiply.

= (17/12) * (24/1) • 3 1/44) (7/10 - 2/5) • (3/4) * (2/13)

Step 4: Simplify the fractions.

= (17/12) * (24/1) • (133/44) (1/2) • (3/4) * (2/13)

Step 5: Multiply the fractions.

= (17/12) * (24/1) • (133/44) * (1/2) • (3/4) * (2/13)

Step 6: Simplify further.

= (17/1) • (133/44) • (1/2) • (1/1) • (1/2) • (3/4) • (2/13)

Step 7: Multiply the numbers.

= 17 • 133 • 1 • 1 • 1 • 3 • 2 / (1 • 44 • 2 • 1 • 2 • 4 • 13)

Step 8: Calculate the numerator and denominator separately.

= 17 * 133 * 3 * 2 / (1 * 44 * 2 * 4 * 13)

Step 9: Calculate the result.

= 22,578 / 1,144

Step 10: Simplify the fraction, if possible.

The result is approximately:

= 19.7366

So, the simplified value of the given expression is approximately 19.7366.
