Yechim qadamlari

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{1}{60} ni \frac{1}{32} ga ko‘paytiring.

$$\frac{-1}{60\times 32}+\frac{1}{12}\times \frac{1}{8}$$

\frac{-1}{60\times 32} kasridagi ko‘paytirishlarni bajaring.

$$\frac{-1}{1920}+\frac{1}{12}\times \frac{1}{8}$$

\frac{-1}{1920} kasri manfiy belgini olib tashlash bilan -\frac{1}{1920} sifatida qayta yozilishi mumkin.

$$-\frac{1}{1920}+\frac{1}{12}\times \frac{1}{8}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{1}{12} ni \frac{1}{8} ga ko‘paytiring.

$$-\frac{1}{1920}+\frac{1\times 1}{12\times 8}$$

\frac{1\times 1}{12\times 8} kasridagi ko‘paytirishlarni bajaring.

$$-\frac{1}{1920}+\frac{1}{96}$$

1920 va 96 ning eng kichik umumiy karralisi 1920 ga teng. -\frac{1}{1920} va \frac{1}{96} ni 1920 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{1}{1920}+\frac{20}{1920}$$

-\frac{1}{1920} va \frac{20}{1920} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-1+20}{1920}$$

19 olish uchun -1 va 20'ni qo'shing.

$$\frac{19}{1920}$$
