1/2-(-3)=6/5+4/9(-3/8)-1 eching

$$\frac { 1 } { 2 } - ( - 3 ) = \frac { 6 } { 5 } + \frac { 4 } { 9 } ( - \frac { 3 } { 8 } ) - 1$$

Tasdiqlamoq

Yechim qadamlari

-3 ning teskarisi 3 ga teng.

$$\frac{1}{2}+3=\frac{6}{5}+\frac{4}{9}\left(-\frac{3}{8}\right)-1$$

3 ni \frac{6}{2} kasrga o‘giring.

$$\frac{1}{2}+\frac{6}{2}=\frac{6}{5}+\frac{4}{9}\left(-\frac{3}{8}\right)-1$$

\frac{1}{2} va \frac{6}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{1+6}{2}=\frac{6}{5}+\frac{4}{9}\left(-\frac{3}{8}\right)-1$$

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

$$\frac{7}{2}=\frac{6}{5}+\frac{4}{9}\left(-\frac{3}{8}\right)-1$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{4}{9} ni -\frac{3}{8} ga ko‘paytiring.

$$\frac{7}{2}=\frac{6}{5}+\frac{4\left(-3\right)}{9\times 8}-1$$

\frac{4\left(-3\right)}{9\times 8} kasridagi ko‘paytirishlarni bajaring.

$$\frac{7}{2}=\frac{6}{5}+\frac{-12}{72}-1$$

\frac{-12}{72} ulushini 12 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{7}{2}=\frac{6}{5}-\frac{1}{6}-1$$

5 va 6 ning eng kichik umumiy karralisi 30 ga teng. \frac{6}{5} va \frac{1}{6} ni 30 maxraj bilan kasrlarga aylantirib oling.

$$\frac{7}{2}=\frac{36}{30}-\frac{5}{30}-1$$

\frac{36}{30} va \frac{5}{30} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{7}{2}=\frac{36-5}{30}-1$$

31 olish uchun 36 dan 5 ni ayirish.

$$\frac{7}{2}=\frac{31}{30}-1$$

1 ni \frac{30}{30} kasrga o‘giring.

$$\frac{7}{2}=\frac{31}{30}-\frac{30}{30}$$

\frac{31}{30} va \frac{30}{30} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{7}{2}=\frac{31-30}{30}$$

1 olish uchun 31 dan 30 ni ayirish.

$$\frac{7}{2}=\frac{1}{30}$$

2 va 30 ning eng kichik umumiy karralisi 30 ga teng. \frac{7}{2} va \frac{1}{30} ni 30 maxraj bilan kasrlarga aylantirib oling.

$$\frac{105}{30}=\frac{1}{30}$$

\frac{105}{30} va \frac{1}{30} ni taqqoslang.

$$\text{false}$$
