5/6+(-4/3)+3/8 eching

$$\frac { 5 } { 6 } + ( - \frac { 4 } { 3 } ) + \frac { 3 } { 8 }$$

Baholash

$$-\frac{1}{8}=-0,125$$

Yechim qadamlari

6 va 3 ning eng kichik umumiy karralisi 6 ga teng. \frac{5}{6} va \frac{4}{3} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$\frac{5}{6}-\frac{8}{6}+\frac{3}{8}$$

\frac{5}{6} va \frac{8}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{5-8}{6}+\frac{3}{8}$$

-3 olish uchun 5 dan 8 ni ayirish.

$$\frac{-3}{6}+\frac{3}{8}$$

\frac{-3}{6} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{1}{2}+\frac{3}{8}$$

2 va 8 ning eng kichik umumiy karralisi 8 ga teng. -\frac{1}{2} va \frac{3}{8} ni 8 maxraj bilan kasrlarga aylantirib oling.

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

-\frac{4}{8} va \frac{3}{8} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

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

-1 olish uchun -4 va 3'ni qo'shing.

$$-\frac{1}{8}$$

Omil

$$-\frac{1}{8} = -0,125$$
