Yechim qadamlari

2 va 4 ning eng kichik umumiy karralisi 4 ga teng. \frac{1}{2} va \frac{3}{4} ni 4 maxraj bilan kasrlarga aylantirib oling.

$$\frac{\frac{2}{4}-\frac{3}{4}-\frac{1}{12}}{\left(-\frac{1}{2}\right)^{2}}$$

\frac{2}{4} va \frac{3}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{\frac{2-3}{4}-\frac{1}{12}}{\left(-\frac{1}{2}\right)^{2}}$$

-1 olish uchun 2 dan 3 ni ayirish.

$$\frac{-\frac{1}{4}-\frac{1}{12}}{\left(-\frac{1}{2}\right)^{2}}$$

4 va 12 ning eng kichik umumiy karralisi 12 ga teng. -\frac{1}{4} va \frac{1}{12} ni 12 maxraj bilan kasrlarga aylantirib oling.

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

-\frac{3}{12} va \frac{1}{12} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

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

-4 olish uchun -3 dan 1 ni ayirish.

$$\frac{\frac{-4}{12}}{\left(-\frac{1}{2}\right)^{2}}$$

\frac{-4}{12} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{-\frac{1}{3}}{\left(-\frac{1}{2}\right)^{2}}$$

2 daraja ko‘rsatkichini -\frac{1}{2} ga hisoblang va \frac{1}{4} ni qiymatni oling.

$$\frac{-\frac{1}{3}}{\frac{1}{4}}$$

-\frac{1}{3} ni \frac{1}{4} ga bo'lish -\frac{1}{3} ga k'paytirish \frac{1}{4} ga qaytarish.

$$-\frac{1}{3}\times 4$$

-\frac{1}{3}\times 4 ni yagona kasrga aylantiring.

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

\frac{-4}{3} kasri manfiy belgini olib tashlash bilan -\frac{4}{3} sifatida qayta yozilishi mumkin.

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

Omil

$$-\frac{4}{3} = -1\frac{1}{3} = -1,3333333333333333$$
