$$\frac{168}{25}\times \frac{7}{3}-3,72\times \frac{2\times 3+1}{3}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{168}{25} ni \frac{7}{3} ga ko‘paytiring.

$$\frac{168\times 7}{25\times 3}-3,72\times \frac{2\times 3+1}{3}$$

\frac{168\times 7}{25\times 3} kasridagi ko‘paytirishlarni bajaring.

$$\frac{1176}{75}-3,72\times \frac{2\times 3+1}{3}$$

\frac{1176}{75} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{392}{25}-3,72\times \frac{2\times 3+1}{3}$$

6 hosil qilish uchun 2 va 3 ni ko'paytirish.

$$\frac{392}{25}-3,72\times \frac{6+1}{3}$$

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

$$\frac{392}{25}-3,72\times \frac{7}{3}$$

3,72 o‘nlik raqamni uning \frac{372}{100} kasrga o‘giring. \frac{372}{100} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{392}{25}-\frac{93}{25}\times \frac{7}{3}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{93}{25} ni \frac{7}{3} ga ko‘paytiring.

$$\frac{392}{25}-\frac{93\times 7}{25\times 3}$$

\frac{93\times 7}{25\times 3} kasridagi ko‘paytirishlarni bajaring.

$$\frac{392}{25}-\frac{651}{75}$$

\frac{651}{75} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{392}{25}-\frac{217}{25}$$

\frac{392}{25} va \frac{217}{25} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{392-217}{25}$$

175 olish uchun 392 dan 217 ni ayirish.

$$\frac{175}{25}$$

7 ni olish uchun 175 ni 25 ga bo‘ling.
