Yechim qadamlari

75 hosil qilish uchun 15 va 5 ni ko'paytirish.

$$\frac{75+2}{5}-\frac{6\times 5+3}{5}-\frac{6\times 4+3}{4}$$

77 olish uchun 75 va 2'ni qo'shing.

$$\frac{77}{5}-\frac{6\times 5+3}{5}-\frac{6\times 4+3}{4}$$

30 hosil qilish uchun 6 va 5 ni ko'paytirish.

$$\frac{77}{5}-\frac{30+3}{5}-\frac{6\times 4+3}{4}$$

33 olish uchun 30 va 3'ni qo'shing.

$$\frac{77}{5}-\frac{33}{5}-\frac{6\times 4+3}{4}$$

\frac{77}{5} va \frac{33}{5} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{77-33}{5}-\frac{6\times 4+3}{4}$$

44 olish uchun 77 dan 33 ni ayirish.

$$\frac{44}{5}-\frac{6\times 4+3}{4}$$

24 hosil qilish uchun 6 va 4 ni ko'paytirish.

$$\frac{44}{5}-\frac{24+3}{4}$$

27 olish uchun 24 va 3'ni qo'shing.

$$\frac{44}{5}-\frac{27}{4}$$

5 va 4 ning eng kichik umumiy karralisi 20 ga teng. \frac{44}{5} va \frac{27}{4} ni 20 maxraj bilan kasrlarga aylantirib oling.

$$\frac{176}{20}-\frac{135}{20}$$

\frac{176}{20} va \frac{135}{20} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{176-135}{20}$$

41 olish uchun 176 dan 135 ni ayirish.

$$\frac{41}{20}$$

Omil

$$\frac{41}{2 ^ {2} \cdot 5} = 2\frac{1}{20} = 2,05$$
