M) 43/6 + 1/43 * 2/1 * 3/41 : 24/43

Решение:

1. \( \frac{1}{43} \times \frac{2}{1} = \frac{2}{43} \)
2. \( \frac{2}{43} \times \frac{3}{41} = \frac{6}{1763} \)
3. \( \frac{6}{1763} : \frac{24}{43} = \frac{6}{1763} \times \frac{43}{24} = \frac{1}{41 \times 24} = \frac{1}{984} \)
4. \( \frac{43}{6} + \frac{1}{984} = \frac{43 \times 164}{984} + \frac{1}{984} = \frac{7052+1}{984} = \frac{7053}{984} = 7\frac{225}{984} \)

Ответ: \( 7\frac{225}{984} \)
