Yechim qadamlari

5 va 10 ning eng kichik umumiy karralisi 10 ga teng. \frac{3}{5} va \frac{1}{10} ni 10 maxraj bilan kasrlarga aylantirib oling.

$$\frac{\frac{6}{10}+\frac{1}{10}}{\frac{-14}{15}}$$

\frac{6}{10} va \frac{1}{10} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{\frac{6+1}{10}}{\frac{-14}{15}}$$

7 olish uchun 6 va 1'ni qo'shing.

$$\frac{\frac{7}{10}}{\frac{-14}{15}}$$

\frac{-14}{15} kasri manfiy belgini olib tashlash bilan -\frac{14}{15} sifatida qayta yozilishi mumkin.

$$\frac{\frac{7}{10}}{-\frac{14}{15}}$$

\frac{7}{10} ni -\frac{14}{15} ga bo'lish \frac{7}{10} ga k'paytirish -\frac{14}{15} ga qaytarish.

$$\frac{7}{10}\left(-\frac{15}{14}\right)$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{7}{10} ni -\frac{15}{14} ga ko‘paytiring.

$$\frac{7\left(-15\right)}{10\times 14}$$

\frac{7\left(-15\right)}{10\times 14} kasridagi ko‘paytirishlarni bajaring.

$$\frac{-105}{140}$$

\frac{-105}{140} ulushini 35 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{3}{4}$$

Omil

$$-\frac{3}{4} = -0,75$$
