Yechim qadamlari

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

$$72\times \frac{6+1}{3}-3,72\times \frac{2\times 3+1}{3}$$

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

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

72\times \frac{7}{3} ni yagona kasrga aylantiring.

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

504 hosil qilish uchun 72 va 7 ni ko'paytirish.

$$\frac{504}{3}-3,72\times \frac{2\times 3+1}{3}$$

168 ni olish uchun 504 ni 3 ga bo‘ling.

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

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

$$168-3,72\times \frac{6+1}{3}$$

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

$$168-3,72\times \frac{7}{3}$$

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.

$$168-\frac{93}{25}\times \frac{7}{3}$$

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

$$168-\frac{93\times 7}{25\times 3}$$

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

$$168-\frac{651}{75}$$

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

$$168-\frac{217}{25}$$

168 ni \frac{4200}{25} kasrga o‘giring.

$$\frac{4200}{25}-\frac{217}{25}$$

\frac{4200}{25} va \frac{217}{25} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{4200-217}{25}$$

3983 olish uchun 4200 dan 217 ni ayirish.

$$\frac{3983}{25}$$

Omil

$$\frac{7 \cdot 569}{5 ^ {2}} = 159\frac{8}{25} = 159,32$$
