12. \(\frac{4}{7}\) qismi 24 ga teng bo'lgan sonni toping.

Sonning \( \frac{m}{n} \) qismi \( a \) ga teng bo'lsa, u holda sonni quyidagicha topish mumkin: \( x = a \div \frac{m}{n} = a \times \frac{n}{m} \).

Masalada berilgan:

• \( \frac{m}{n} = \frac{4}{7} \)
• \( a = 24 \)

Sonni topamiz:

\( x = 24 \div \frac{4}{7} = 24 \times \frac{7}{4} = \frac{24 \times 7}{4} = 6 \times 7 = 42 \)
