Yechim qadamlari

3 va 5 ning eng kichik umumiy karralisi 15 ga teng. \frac{2}{3} va \frac{1}{5} ni 15 maxraj bilan kasrlarga aylantirib oling.

$$\left(\frac{10}{15}+\frac{3}{15}\right)\times \frac{5}{2}+\frac{5}{6}$$

\frac{10}{15} va \frac{3}{15} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{10+3}{15}\times \frac{5}{2}+\frac{5}{6}$$

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

$$\frac{13}{15}\times \frac{5}{2}+\frac{5}{6}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{13}{15} ni \frac{5}{2} ga ko‘paytiring.

$$\frac{13\times 5}{15\times 2}+\frac{5}{6}$$

\frac{13\times 5}{15\times 2} kasridagi ko‘paytirishlarni bajaring.

$$\frac{65}{30}+\frac{5}{6}$$

\frac{65}{30} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{13}{6}+\frac{5}{6}$$

\frac{13}{6} va \frac{5}{6} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{13+5}{6}$$

18 olish uchun 13 va 5'ni qo'shing.

$$\frac{18}{6}$$

3 ni olish uchun 18 ni 6 ga bo‘ling.
