9/4-(4-9/4)=5(9+1+9/4)/4 eching

$$\frac { 9 } { 4 } - ( 4 - \frac { 9 } { 4 } ) = 5 \frac { ( 9 + 1 + \frac { 9 } { 4 } ) } { 4 }$$

Tasdiqlamoq

Yechim qadamlari

Tenglamaning ikkala tarafini 4 ga ko'paytirish.

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

4 ni \frac{16}{4} kasrga o‘giring.

$$9-4\left(\frac{16}{4}-\frac{9}{4}\right)=5\left(9+1+\frac{9}{4}\right)$$

\frac{16}{4} va \frac{9}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$9-4\times \frac{16-9}{4}=5\left(9+1+\frac{9}{4}\right)$$

7 olish uchun 16 dan 9 ni ayirish.

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

4 va 4 ni qisqartiring.

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

2 olish uchun 9 dan 7 ni ayirish.

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

10 olish uchun 9 va 1'ni qo'shing.

$$2=5\left(10+\frac{9}{4}\right)$$

10 ni \frac{40}{4} kasrga o‘giring.

$$2=5\left(\frac{40}{4}+\frac{9}{4}\right)$$

\frac{40}{4} va \frac{9}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$2=5\times \frac{40+9}{4}$$

49 olish uchun 40 va 9'ni qo'shing.

$$2=5\times \frac{49}{4}$$

5\times \frac{49}{4} ni yagona kasrga aylantiring.

$$2=\frac{5\times 49}{4}$$

245 hosil qilish uchun 5 va 49 ni ko'paytirish.

$$2=\frac{245}{4}$$

2 ni \frac{8}{4} kasrga o‘giring.

$$\frac{8}{4}=\frac{245}{4}$$

\frac{8}{4} va \frac{245}{4} ni taqqoslang.

$$\text{false}$$
