Yechim qadamlari

4\left(-\frac{1}{14}\right) ni yagona kasrga aylantiring.

$$3\left(\frac{4\left(-1\right)}{14}+1\right)$$

-4 hosil qilish uchun 4 va -1 ni ko'paytirish.

$$3\left(\frac{-4}{14}+1\right)$$

\frac{-4}{14} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$3\left(-\frac{2}{7}+1\right)$$

1 ni \frac{7}{7} kasrga o‘giring.

$$3\left(-\frac{2}{7}+\frac{7}{7}\right)$$

-\frac{2}{7} va \frac{7}{7} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$3\times \frac{-2+7}{7}$$

5 olish uchun -2 va 7'ni qo'shing.

$$3\times \frac{5}{7}$$

3\times \frac{5}{7} ni yagona kasrga aylantiring.

$$\frac{3\times 5}{7}$$

15 hosil qilish uchun 3 va 5 ni ko'paytirish.

$$\frac{15}{7}$$

Omil

$$\frac{3 \cdot 5}{7} = 2\frac{1}{7} = 2,142857142857143$$
