Answer 2

To simplify the expression (1/4 - 5/6) ÷ (2.1/3 + 1/6 × 3/4), you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right). In this case, there are no parentheses, exponents, or square roots, so we'll perform the operations in the following order:

1. First, simplify the fractions inside the expression:

   (1/4 - 5/6) ÷ (2.1/3 + 1/6 × 3/4)

   To subtract fractions, you need a common denominator, which in this case is 12:

   (3/12 - 10/12) ÷ (2.1/3 + 1/6 × 3/4)

   Now, subtract the fractions in the numerator:

   (-7/12) ÷ (2.1/3 + 1/6 × 3/4)

2. Next, perform any multiplications and divisions:

   (-7/12) ÷ (2.1/3 + 1/6 × 3/4)

   To divide by a fraction, you can multiply by its reciprocal. So, divide by (2.1/3) is the same as multiplying by (3/2.1):

   (-7/12) × (3/2.1 + 1/6 × 3/4)

   Now, let's simplify the terms inside the parentheses:

   (-7/12) × (1.42857 + 0.125)

   (-7/12) × (1.55357)

3. Finally, perform the multiplication:

   (-7/12) × (1.55357)

   ≈ -0.9114 (rounded to four decimal places)

So, the simplified value of the expression is approximately -0.9114.
