Yechim qadamlari

\frac{-1}{12} kasri manfiy belgini olib tashlash bilan -\frac{1}{12} sifatida qayta yozilishi mumkin.

$$-\frac{1}{12}-\frac{\frac{7}{12}\times \frac{2}{3}}{\frac{4}{3}}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{7}{12} ni \frac{2}{3} ga ko‘paytiring.

$$-\frac{1}{12}-\frac{\frac{7\times 2}{12\times 3}}{\frac{4}{3}}$$

\frac{7\times 2}{12\times 3} kasridagi ko‘paytirishlarni bajaring.

$$-\frac{1}{12}-\frac{\frac{14}{36}}{\frac{4}{3}}$$

\frac{14}{36} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{1}{12}-\frac{\frac{7}{18}}{\frac{4}{3}}$$

\frac{7}{18} ni \frac{4}{3} ga bo'lish \frac{7}{18} ga k'paytirish \frac{4}{3} ga qaytarish.

$$-\frac{1}{12}-\frac{7}{18}\times \frac{3}{4}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{7}{18} ni \frac{3}{4} ga ko‘paytiring.

$$-\frac{1}{12}-\frac{7\times 3}{18\times 4}$$

\frac{7\times 3}{18\times 4} kasridagi ko‘paytirishlarni bajaring.

$$-\frac{1}{12}-\frac{21}{72}$$

\frac{21}{72} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{1}{12}-\frac{7}{24}$$

12 va 24 ning eng kichik umumiy karralisi 24 ga teng. -\frac{1}{12} va \frac{7}{24} ni 24 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{2}{24}-\frac{7}{24}$$

-\frac{2}{24} va \frac{7}{24} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-2-7}{24}$$

-9 olish uchun -2 dan 7 ni ayirish.

$$\frac{-9}{24}$$

\frac{-9}{24} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{3}{8}$$

Omil

$$-\frac{3}{8} = -0,375$$
