Ответ:

1) 8/7 - 1/14 + 1/42= 16/14 - 1/14 + 1/42= 15/14 + 1/42 = 45/42 + 1/42 = 46/42

2) 46/42 × 12/46 = 2/7

Answer 2

To solve the given expression:

(8/7 - 1/14 + 1/42) * 12/46

Let's simplify the expression step by step:

1. Simplify the fractions: 8/7 - 1/14 + 1/42 = (96/84) - (6/84) + (2/84) = (96 - 6 + 2)/84 = 92/84

2. Multiply by 12/46: (92/84) * (12/46) = (92 * 12) / (84 * 46) = 1104 / 3864

3. Simplify the fraction: 1104/3864 = (4 * 276) / (4 * 966) = 276 / 966

Therefore, the simplified form of the expression (8/7 - 1/14 + 1/42) * 12/46 is 276/966.
