Yechim qadamlari

\frac{1\times 9+5}{9} ni \frac{2\times 3+1}{3} ga bo'lish \frac{1\times 9+5}{9} ga k'paytirish \frac{2\times 3+1}{3} ga qaytarish.

$$\frac{\left(1\times 9+5\right)\times 3}{9\left(2\times 3+1\right)}-\left(-325\times \frac{5}{13}\right)$$

Surat va maxrajdagi ikkala 3 ni qisqartiring.

$$\frac{5+9}{3\left(1+2\times 3\right)}-\left(-325\times \frac{5}{13}\right)$$

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

$$\frac{14}{3\left(1+2\times 3\right)}-\left(-325\times \frac{5}{13}\right)$$

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

$$\frac{14}{3\left(1+6\right)}-\left(-325\times \frac{5}{13}\right)$$

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

$$\frac{14}{3\times 7}-\left(-325\times \frac{5}{13}\right)$$

21 hosil qilish uchun 3 va 7 ni ko'paytirish.

$$\frac{14}{21}-\left(-325\times \frac{5}{13}\right)$$

\frac{14}{21} ulushini 7 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{2}{3}-\left(-325\times \frac{5}{13}\right)$$

-325\times \frac{5}{13} ni yagona kasrga aylantiring.

$$\frac{2}{3}-\frac{-325\times 5}{13}$$

-1625 hosil qilish uchun -325 va 5 ni ko'paytirish.

$$\frac{2}{3}-\frac{-1625}{13}$$

-125 ni olish uchun -1625 ni 13 ga bo‘ling.

$$\frac{2}{3}-\left(-125\right)$$

-125 ning teskarisi 125 ga teng.

$$\frac{2}{3}+125$$

125 ni \frac{375}{3} kasrga o‘giring.

$$\frac{2}{3}+\frac{375}{3}$$

\frac{2}{3} va \frac{375}{3} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{2+375}{3}$$

377 olish uchun 2 va 375'ni qo'shing.

$$\frac{377}{3}$$

Omil

$$\frac{13 \cdot 29}{3} = 125\frac{2}{3} = 125,66666666666667$$
