Yechim qadamlari

\frac{1}{2} ni \frac{5}{8} ga bo'lish \frac{1}{2} ga k'paytirish \frac{5}{8} ga qaytarish.

$$\frac{1}{2}\times \frac{8}{5}+\frac{1}{4}\times \frac{3}{5}\times \frac{3}{4}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{1}{2} ni \frac{8}{5} ga ko‘paytiring.

$$\frac{1\times 8}{2\times 5}+\frac{1}{4}\times \frac{3}{5}\times \frac{3}{4}$$

\frac{1\times 8}{2\times 5} kasridagi ko‘paytirishlarni bajaring.

$$\frac{8}{10}+\frac{1}{4}\times \frac{3}{5}\times \frac{3}{4}$$

\frac{8}{10} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

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

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{1}{4} ni \frac{3}{5} ga ko‘paytiring.

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

\frac{1\times 3}{4\times 5} kasridagi ko‘paytirishlarni bajaring.

$$\frac{4}{5}+\frac{3}{20}\times \frac{3}{4}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{3}{20} ni \frac{3}{4} ga ko‘paytiring.

$$\frac{4}{5}+\frac{3\times 3}{20\times 4}$$

\frac{3\times 3}{20\times 4} kasridagi ko‘paytirishlarni bajaring.

$$\frac{4}{5}+\frac{9}{80}$$

5 va 80 ning eng kichik umumiy karralisi 80 ga teng. \frac{4}{5} va \frac{9}{80} ni 80 maxraj bilan kasrlarga aylantirib oling.

$$\frac{64}{80}+\frac{9}{80}$$

\frac{64}{80} va \frac{9}{80} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{64+9}{80}$$

73 olish uchun 64 va 9'ni qo'shing.

$$\frac{73}{80}$$
