(-7/2)+(-1/6)+(-1) eching

$$( - \frac { 7 } { 2 } ) + ( - \frac { 1 } { 6 } ) + ( - 1 )$$

Yechim qadamlari

2 va 6 ning eng kichik umumiy karralisi 6 ga teng. -\frac{7}{2} va \frac{1}{6} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{21}{6}-\frac{1}{6}-1$$

-\frac{21}{6} va \frac{1}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-21-1}{6}-1$$

-22 olish uchun -21 dan 1 ni ayirish.

$$\frac{-22}{6}-1$$

\frac{-22}{6} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{11}{3}-1$$

1 ni \frac{3}{3} kasrga o‘giring.

$$-\frac{11}{3}-\frac{3}{3}$$

-\frac{11}{3} va \frac{3}{3} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-11-3}{3}$$

-14 olish uchun -11 dan 3 ni ayirish.

$$-\frac{14}{3}$$

Omil

$$-\frac{14}{3} = -4\frac{2}{3} = -4,666666666666667$$
