-7/8+-1/2= eching

$$\frac { - 7 } { 8 } + \frac { - 1 } { 2 } =$$

Baholash

$$-\frac{11}{8}=-1,375$$

Yechim qadamlari

\frac{-7}{8} kasri manfiy belgini olib tashlash bilan -\frac{7}{8} sifatida qayta yozilishi mumkin.

$$-\frac{7}{8}+\frac{-1}{2}$$

\frac{-1}{2} kasri manfiy belgini olib tashlash bilan -\frac{1}{2} sifatida qayta yozilishi mumkin.

$$-\frac{7}{8}-\frac{1}{2}$$

8 va 2 ning eng kichik umumiy karralisi 8 ga teng. -\frac{7}{8} va \frac{1}{2} ni 8 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{7}{8}-\frac{4}{8}$$

-\frac{7}{8} va \frac{4}{8} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-7-4}{8}$$

-11 olish uchun -7 dan 4 ni ayirish.

$$-\frac{11}{8}$$

Omil

$$-\frac{11}{8} = -1\frac{3}{8} = -1,375$$
