Yechim qadamlari

270 hosil qilish uchun 27 va 10 ni ko'paytirish.

$$\left(\frac{\frac{270+3}{10}-13,4\times 2}{-\frac{1}{8}}-12\right)\times 3$$

273 olish uchun 270 va 3'ni qo'shing.

$$\left(\frac{\frac{273}{10}-13,4\times 2}{-\frac{1}{8}}-12\right)\times 3$$

26,8 hosil qilish uchun 13,4 va 2 ni ko'paytirish.

$$\left(\frac{\frac{273}{10}-26,8}{-\frac{1}{8}}-12\right)\times 3$$

26,8 o‘nlik raqamni uning \frac{268}{10} kasrga o‘giring. \frac{268}{10} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\left(\frac{\frac{273}{10}-\frac{134}{5}}{-\frac{1}{8}}-12\right)\times 3$$

10 va 5 ning eng kichik umumiy karralisi 10 ga teng. \frac{273}{10} va \frac{134}{5} ni 10 maxraj bilan kasrlarga aylantirib oling.

$$\left(\frac{\frac{273}{10}-\frac{268}{10}}{-\frac{1}{8}}-12\right)\times 3$$

\frac{273}{10} va \frac{268}{10} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\left(\frac{\frac{273-268}{10}}{-\frac{1}{8}}-12\right)\times 3$$

5 olish uchun 273 dan 268 ni ayirish.

$$\left(\frac{\frac{5}{10}}{-\frac{1}{8}}-12\right)\times 3$$

\frac{5}{10} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\left(\frac{\frac{1}{2}}{-\frac{1}{8}}-12\right)\times 3$$

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

$$\left(\frac{1}{2}\left(-8\right)-12\right)\times 3$$

\frac{-8}{2} hosil qilish uchun \frac{1}{2} va -8 ni ko'paytirish.

$$\left(\frac{-8}{2}-12\right)\times 3$$

-4 ni olish uchun -8 ni 2 ga bo‘ling.

$$\left(-4-12\right)\times 3$$

-16 olish uchun -4 dan 12 ni ayirish.

$$-16\times 3$$

-48 hosil qilish uchun -16 va 3 ni ko'paytirish.
