Yechim qadamlari

\frac{5}{8} ni \frac{3}{4} ga bo'lish \frac{5}{8} ga k'paytirish \frac{3}{4} ga qaytarish.

$$\frac{1}{7}+\frac{5}{8}\times \frac{4}{3}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{5}{8} ni \frac{4}{3} ga ko‘paytiring.

$$\frac{1}{7}+\frac{5\times 4}{8\times 3}$$

\frac{5\times 4}{8\times 3} kasridagi ko‘paytirishlarni bajaring.

$$\frac{1}{7}+\frac{20}{24}$$

\frac{20}{24} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{1}{7}+\frac{5}{6}$$

7 va 6 ning eng kichik umumiy karralisi 42 ga teng. \frac{1}{7} va \frac{5}{6} ni 42 maxraj bilan kasrlarga aylantirib oling.

$$\frac{6}{42}+\frac{35}{42}$$

\frac{6}{42} va \frac{35}{42} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{6+35}{42}$$

41 olish uchun 6 va 35'ni qo'shing.

$$\frac{41}{42}$$
