Yechim qadamlari

\frac{2\times 4+3}{4} ni \frac{1}{7} ga bo'lish \frac{2\times 4+3}{4} ga k'paytirish \frac{1}{7} ga qaytarish.

$$\frac{\frac{\left(2\times 4+3\right)\times 7}{4}-22}{6-\left(-5\right)}$$

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

$$\frac{\frac{\left(8+3\right)\times 7}{4}-22}{6-\left(-5\right)}$$

11 olish uchun 8 va 3'ni qo'shing.

$$\frac{\frac{11\times 7}{4}-22}{6-\left(-5\right)}$$

77 hosil qilish uchun 11 va 7 ni ko'paytirish.

$$\frac{\frac{77}{4}-22}{6-\left(-5\right)}$$

22 ni \frac{88}{4} kasrga o‘giring.

$$\frac{\frac{77}{4}-\frac{88}{4}}{6-\left(-5\right)}$$

\frac{77}{4} va \frac{88}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{\frac{77-88}{4}}{6-\left(-5\right)}$$

-11 olish uchun 77 dan 88 ni ayirish.

$$\frac{-\frac{11}{4}}{6-\left(-5\right)}$$

-5 ning teskarisi 5 ga teng.

$$\frac{-\frac{11}{4}}{6+5}$$

11 olish uchun 6 va 5'ni qo'shing.

$$\frac{-\frac{11}{4}}{11}$$

\frac{-\frac{11}{4}}{11} ni yagona kasrga aylantiring.

$$\frac{-11}{4\times 11}$$

44 hosil qilish uchun 4 va 11 ni ko'paytirish.

$$\frac{-11}{44}$$

\frac{-11}{44} ulushini 11 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{1}{4}$$

Omil

$$-\frac{1}{4} = -0,25$$
