Yechim qadamlari

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

$$\frac{4}{4\times 2}-2+\frac{\frac{3}{4}}{4}$$

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

$$\frac{4}{8}-2+\frac{\frac{3}{4}}{4}$$

\frac{4}{8} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{1}{2}-2+\frac{\frac{3}{4}}{4}$$

2 ni \frac{4}{2} kasrga o‘giring.

$$\frac{1}{2}-\frac{4}{2}+\frac{\frac{3}{4}}{4}$$

\frac{1}{2} va \frac{4}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{1-4}{2}+\frac{\frac{3}{4}}{4}$$

-3 olish uchun 1 dan 4 ni ayirish.

$$-\frac{3}{2}+\frac{\frac{3}{4}}{4}$$

\frac{\frac{3}{4}}{4} ni yagona kasrga aylantiring.

$$-\frac{3}{2}+\frac{3}{4\times 4}$$

16 hosil qilish uchun 4 va 4 ni ko'paytirish.

$$-\frac{3}{2}+\frac{3}{16}$$

2 va 16 ning eng kichik umumiy karralisi 16 ga teng. -\frac{3}{2} va \frac{3}{16} ni 16 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{24}{16}+\frac{3}{16}$$

-\frac{24}{16} va \frac{3}{16} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-24+3}{16}$$

-21 olish uchun -24 va 3'ni qo'shing.

$$-\frac{21}{16}$$

Omil

$$-\frac{21}{16} = -1\frac{5}{16} = -1,3125$$
