Yechim qadamlari

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{2}{3} ni \frac{1}{2} ga ko‘paytiring.

$$\frac{\frac{2\times 1}{3\times 2}+\frac{1}{4}}{\frac{1}{3}}$$

Surat va maxrajdagi ikkala 2 ni qisqartiring.

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

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.

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

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

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

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

$$\frac{\frac{7}{12}}{\frac{1}{3}}$$

\frac{7}{12} ni \frac{1}{3} ga bo'lish \frac{7}{12} ga k'paytirish \frac{1}{3} ga qaytarish.

$$\frac{7}{12}\times 3$$

\frac{7}{12}\times 3 ni yagona kasrga aylantiring.

$$\frac{7\times 3}{12}$$

21 hosil qilish uchun 7 va 3 ni ko'paytirish.

$$\frac{21}{12}$$

\frac{21}{12} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{7}{4}$$

Omil

$$\frac{7}{2 ^ {2}} = 1\frac{3}{4} = 1,75$$
