Answer 2

To simplify the expression (4—2ц 5/6—5/12)×(7ц 1/12—5ц 3/4), let's break it down step by step:

First, let's simplify the expressions inside the parentheses:

4—2ц 5/6—5/12 = 4 - (2 + 5/6 - 5/12)

To subtract fractions, we need to find a common denominator. In this case, the least common denominator (LCD) is 12:

4 - (2 + 5/6 - 5/12) = 4 - (12/6 + 5/6 - 5/12) = 4 - (24/12 + 5/6 - 5/12) = 4 - (29/12 - 5/12) = 4 - (24/12) = 4 - 2 = 2

Next, let's simplify the second expression inside the parentheses:

7ц 1/12—5ц 3/4 = (7 + 1/12) - (5 + 3/4)

To subtract mixed numbers, we need to convert them to improper fractions:

(7 + 1/12) - (5 + 3/4) = (84/12 + 1/12) - (20/4 + 3/4) = (85/12) - (23/4)

Now, let's find a common denominator. The LCD is 12:

(85/12) - (23/4) = (85/12) - (69/12) = 16/12 = 4/3

Finally, let's multiply the results:

2 × (4/3) = 8/3

Therefore, the simplified expression (4—2ц 5/6—5/12)×(7ц 1/12—5ц 3/4) is equal to 8/3.
