12/frac{1{2}+1/3} eching

$$\frac{ 12 }{ \frac{ 1 }{ 2 } + \frac{ 1 }{ 3 } }$$

Baholash

$$\frac{72}{5}=14,4$$

Yechim qadamlari

2 va 3 ning eng kichik umumiy karralisi 6 ga teng. \frac{1}{2} va \frac{1}{3} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$\frac{12}{\frac{3}{6}+\frac{2}{6}}$$

\frac{3}{6} va \frac{2}{6} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{12}{\frac{3+2}{6}}$$

5 olish uchun 3 va 2'ni qo'shing.

$$\frac{12}{\frac{5}{6}}$$

12 ni \frac{5}{6} ga bo'lish 12 ga k'paytirish \frac{5}{6} ga qaytarish.

$$12\times \frac{6}{5}$$

12\times \frac{6}{5} ni yagona kasrga aylantiring.

$$\frac{12\times 6}{5}$$

72 hosil qilish uchun 12 va 6 ni ko'paytirish.

$$\frac{72}{5}$$

Omil

$$\frac{2 ^ {3} \cdot 3 ^ {2}}{5} = 14\frac{2}{5} = 14,4$$
