Yechim qadamlari

12 va 4 ning eng kichik umumiy karralisi 12 ga teng. \frac{7}{12} va \frac{1}{4} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$48\left(\frac{7}{12}+\frac{3}{12}\right)$$

\frac{7}{12} va \frac{3}{12} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$48\times \frac{7+3}{12}$$

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

$$48\times \frac{10}{12}$$

\frac{10}{12} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$48\times \frac{5}{6}$$

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

$$\frac{48\times 5}{6}$$

240 hosil qilish uchun 48 va 5 ni ko'paytirish.

$$\frac{240}{6}$$

40 ni olish uchun 240 ni 6 ga bo‘ling.
