Yechim qadamlari

5 hosil qilish uchun 1 va 5 ni ko'paytirish.

$$\frac{5+1}{5}\left(-\frac{2}{3}\right)-\frac{\frac{1\times 3+2}{3}}{-\frac{2\times 9+2}{9}}$$

6 olish uchun 5 va 1'ni qo'shing.

$$\frac{6}{5}\left(-\frac{2}{3}\right)-\frac{\frac{1\times 3+2}{3}}{-\frac{2\times 9+2}{9}}$$

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

$$\frac{6\left(-2\right)}{5\times 3}-\frac{\frac{1\times 3+2}{3}}{-\frac{2\times 9+2}{9}}$$

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

$$\frac{-12}{15}-\frac{\frac{1\times 3+2}{3}}{-\frac{2\times 9+2}{9}}$$

\frac{-12}{15} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{4}{5}-\frac{\frac{1\times 3+2}{3}}{-\frac{2\times 9+2}{9}}$$

3 hosil qilish uchun 1 va 3 ni ko'paytirish.

$$-\frac{4}{5}-\frac{\frac{3+2}{3}}{-\frac{2\times 9+2}{9}}$$

5 olish uchun 3 va 2'ni qo'shing.

$$-\frac{4}{5}-\frac{\frac{5}{3}}{-\frac{2\times 9+2}{9}}$$

18 hosil qilish uchun 2 va 9 ni ko'paytirish.

$$-\frac{4}{5}-\frac{\frac{5}{3}}{-\frac{18+2}{9}}$$

20 olish uchun 18 va 2'ni qo'shing.

$$-\frac{4}{5}-\frac{\frac{5}{3}}{-\frac{20}{9}}$$

\frac{5}{3} ni -\frac{20}{9} ga bo'lish \frac{5}{3} ga k'paytirish -\frac{20}{9} ga qaytarish.

$$-\frac{4}{5}-\frac{5}{3}\left(-\frac{9}{20}\right)$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{5}{3} ni -\frac{9}{20} ga ko‘paytiring.

$$-\frac{4}{5}-\frac{5\left(-9\right)}{3\times 20}$$

\frac{5\left(-9\right)}{3\times 20} kasridagi ko‘paytirishlarni bajaring.

$$-\frac{4}{5}-\frac{-45}{60}$$

\frac{-45}{60} ulushini 15 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{4}{5}-\left(-\frac{3}{4}\right)$$

-\frac{3}{4} ning teskarisi \frac{3}{4} ga teng.

$$-\frac{4}{5}+\frac{3}{4}$$

5 va 4 ning eng kichik umumiy karralisi 20 ga teng. -\frac{4}{5} va \frac{3}{4} ni 20 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{16}{20}+\frac{15}{20}$$

-\frac{16}{20} va \frac{15}{20} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-16+15}{20}$$

-1 olish uchun -16 va 15'ni qo'shing.

$$-\frac{1}{20}$$

Omil

$$-\frac{1}{20} = -0,05$$
