1/3+(-5/6)-(-1/2)-2/3 eching

$$\frac { 1 } { 3 } + ( - \frac { 5 } { 6 } ) - ( - \frac { 1 } { 2 } ) - \frac { 2 } { 3 }$$

Baholash

$$-\frac{2}{3}\approx -0,666666667$$

Yechim qadamlari

3 va 6 ning eng kichik umumiy karralisi 6 ga teng. \frac{1}{3} va \frac{5}{6} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$\frac{2}{6}-\frac{5}{6}-\left(-\frac{1}{2}\right)-\frac{2}{3}$$

\frac{2}{6} va \frac{5}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{2-5}{6}-\left(-\frac{1}{2}\right)-\frac{2}{3}$$

-3 olish uchun 2 dan 5 ni ayirish.

$$\frac{-3}{6}-\left(-\frac{1}{2}\right)-\frac{2}{3}$$

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

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

-\frac{1}{2} ning teskarisi \frac{1}{2} ga teng.

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

0 olish uchun -\frac{1}{2} va \frac{1}{2}'ni qo'shing.

$$0-\frac{2}{3}$$

-\frac{2}{3} olish uchun 0 dan \frac{2}{3} ni ayirish.

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

Omil

$$-\frac{2}{3} = -0,6666666666666666$$
