Answer 3

To simplify this expression, we'll 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).

Here's the expression with the operations broken down:

(1/3/4 * 2/4/7) : (4/1/2 + 2/2/5) : (9/10 * 3/8)

Let's solve it step by step:

1. Simplify the fractions within each group:

   (1/3/4 * 2/4/7) : (4/1/2 + 2/2/5) : (9/10 * 3/8)

   (1/12 * 2/28) : (8/2 + 2/10) : (27/10 * 3/8)

2. Perform the multiplications and additions within each group:

   (1/12 * 2/28) : (4 + 1/5) : (81/80)

3. Continue simplifying:

   (1/336) : (21/5) : (81/80)

4. Now, we'll deal with the division operations from left to right:

   (1/336) / (21/5) / (81/80)

5. To divide fractions, multiply by the reciprocal:

   (1/336) * (5/21) * (80/81)

6. Multiply the fractions together:

   (1 * 5 * 80) / (336 * 21 * 81)

7. Simplify the numerator and denominator:

   (400) / (571536)

So, the simplified result is 400/571536. This fraction can be further reduced, but it's quite a large denominator, and reducing it would result in a complex fraction. If you want a decimal approximation, you can calculate that as well:

400 / 571536 ≈ 0.00069994196
