9 olish uchun 5 va 4'ni qo'shing.

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

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

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

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

$$\frac{9}{5}\times \frac{6}{5}\times \frac{1\times 4+3}{4}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{9}{5} ni \frac{6}{5} ga ko‘paytiring.

$$\frac{9\times 6}{5\times 5}\times \frac{1\times 4+3}{4}$$

\frac{9\times 6}{5\times 5} kasridagi ko‘paytirishlarni bajaring.

$$\frac{54}{25}\times \frac{1\times 4+3}{4}$$

4 hosil qilish uchun 1 va 4 ni ko'paytirish.

$$\frac{54}{25}\times \frac{4+3}{4}$$

7 olish uchun 4 va 3'ni qo'shing.

$$\frac{54}{25}\times \frac{7}{4}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{54}{25} ni \frac{7}{4} ga ko‘paytiring.

$$\frac{54\times 7}{25\times 4}$$

\frac{54\times 7}{25\times 4} kasridagi ko‘paytirishlarni bajaring.

$$\frac{378}{100}$$

\frac{378}{100} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{189}{50}$$

Omil

$$\frac{3 ^ {3} \cdot 7}{2 \cdot 5 ^ {2}} = 3\frac{39}{50} = 3,78$$
