Yechim qadamlari

3 va 4 ning eng kichik umumiy karralisi 12 ga teng. \frac{1}{3} va \frac{1}{4} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$\frac{1}{\frac{4}{12}+\frac{3}{12}}$$

\frac{4}{12} va \frac{3}{12} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{1}{\frac{4+3}{12}}$$

7 olish uchun 4 va 3'ni qo'shing.

$$\frac{1}{\frac{7}{12}}$$

1 ni \frac{7}{12} ga bo'lish 1 ga k'paytirish \frac{7}{12} ga qaytarish.

$$1\times \frac{12}{7}$$

\frac{12}{7} hosil qilish uchun 1 va \frac{12}{7} ni ko'paytirish.

$$\frac{12}{7}$$

Omil

$$\frac{2 ^ {2} \cdot 3}{7} = 1\frac{5}{7} = 1,7142857142857142$$
