Yechim qadamlari

Har qanday son birga bo‘linganda, natija o‘zi chiqadi.

$$8-\frac{1\times 5+1}{5}-\frac{2\times 10+3}{10}-\frac{1\times 2+1}{2}$$

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

$$8-\frac{5+1}{5}-\frac{2\times 10+3}{10}-\frac{1\times 2+1}{2}$$

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

$$8-\frac{6}{5}-\frac{2\times 10+3}{10}-\frac{1\times 2+1}{2}$$

8 ni \frac{40}{5} kasrga o‘giring.

$$\frac{40}{5}-\frac{6}{5}-\frac{2\times 10+3}{10}-\frac{1\times 2+1}{2}$$

\frac{40}{5} va \frac{6}{5} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{40-6}{5}-\frac{2\times 10+3}{10}-\frac{1\times 2+1}{2}$$

34 olish uchun 40 dan 6 ni ayirish.

$$\frac{34}{5}-\frac{2\times 10+3}{10}-\frac{1\times 2+1}{2}$$

20 hosil qilish uchun 2 va 10 ni ko'paytirish.

$$\frac{34}{5}-\frac{20+3}{10}-\frac{1\times 2+1}{2}$$

23 olish uchun 20 va 3'ni qo'shing.

$$\frac{34}{5}-\frac{23}{10}-\frac{1\times 2+1}{2}$$

5 va 10 ning eng kichik umumiy karralisi 10 ga teng. \frac{34}{5} va \frac{23}{10} ni 10 maxraj bilan kasrlarga aylantirib oling.

$$\frac{68}{10}-\frac{23}{10}-\frac{1\times 2+1}{2}$$

\frac{68}{10} va \frac{23}{10} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{68-23}{10}-\frac{1\times 2+1}{2}$$

45 olish uchun 68 dan 23 ni ayirish.

$$\frac{45}{10}-\frac{1\times 2+1}{2}$$

\frac{45}{10} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{9}{2}-\frac{1\times 2+1}{2}$$

2 hosil qilish uchun 1 va 2 ni ko'paytirish.

$$\frac{9}{2}-\frac{2+1}{2}$$

3 olish uchun 2 va 1'ni qo'shing.

$$\frac{9}{2}-\frac{3}{2}$$

\frac{9}{2} va \frac{3}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{9-3}{2}$$

6 olish uchun 9 dan 3 ni ayirish.

$$\frac{6}{2}$$

3 ni olish uchun 6 ni 2 ga bo‘ling.
