(-1/5-1)*(-2+1/2) eching

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

Baholash

$$\frac{9}{5}=1,8$$

Yechim qadamlari

1 ni \frac{5}{5} kasrga o‘giring.

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

-\frac{1}{5} va \frac{5}{5} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

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

-6 olish uchun -1 dan 5 ni ayirish.

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

-2 ni -\frac{4}{2} kasrga o‘giring.

$$-\frac{6}{5}\left(-\frac{4}{2}+\frac{1}{2}\right)$$

-\frac{4}{2} va \frac{1}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$-\frac{6}{5}\times \frac{-4+1}{2}$$

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

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

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{6}{5} ni -\frac{3}{2} ga ko‘paytiring.

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

\frac{-6\left(-3\right)}{5\times 2} kasridagi ko‘paytirishlarni bajaring.

$$\frac{18}{10}$$

\frac{18}{10} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{9}{5}$$

Omil

$$\frac{3 ^ {2}}{5} = 1\frac{4}{5} = 1,8$$
