Yechim qadamlari

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{2}{7} ni -\frac{5}{12} ga ko‘paytiring.

$$\frac{2\left(-5\right)}{7\times 12}-\frac{5}{7}\times \frac{5}{12}-\frac{5}{3}\left(-\frac{1}{4}\right)$$

\frac{2\left(-5\right)}{7\times 12} kasridagi ko‘paytirishlarni bajaring.

$$\frac{-10}{84}-\frac{5}{7}\times \frac{5}{12}-\frac{5}{3}\left(-\frac{1}{4}\right)$$

\frac{-10}{84} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{5}{42}-\frac{5}{7}\times \frac{5}{12}-\frac{5}{3}\left(-\frac{1}{4}\right)$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{5}{7} ni \frac{5}{12} ga ko‘paytiring.

$$-\frac{5}{42}-\frac{5\times 5}{7\times 12}-\frac{5}{3}\left(-\frac{1}{4}\right)$$

\frac{5\times 5}{7\times 12} kasridagi ko‘paytirishlarni bajaring.

$$-\frac{5}{42}-\frac{25}{84}-\frac{5}{3}\left(-\frac{1}{4}\right)$$

42 va 84 ning eng kichik umumiy karralisi 84 ga teng. -\frac{5}{42} va \frac{25}{84} ni 84 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{10}{84}-\frac{25}{84}-\frac{5}{3}\left(-\frac{1}{4}\right)$$

-\frac{10}{84} va \frac{25}{84} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-10-25}{84}-\frac{5}{3}\left(-\frac{1}{4}\right)$$

-35 olish uchun -10 dan 25 ni ayirish.

$$\frac{-35}{84}-\frac{5}{3}\left(-\frac{1}{4}\right)$$

\frac{-35}{84} ulushini 7 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{5}{12}-\frac{5}{3}\left(-\frac{1}{4}\right)$$

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

$$-\frac{5}{12}+\frac{-5\left(-1\right)}{3\times 4}$$

\frac{-5\left(-1\right)}{3\times 4} kasridagi ko‘paytirishlarni bajaring.

$$-\frac{5}{12}+\frac{5}{12}$$

0 olish uchun -\frac{5}{12} va \frac{5}{12}'ni qo'shing.
