Yechim qadamlari

\frac{3\times 4+1}{4} ni \frac{2\times 2+1}{2} ga bo'lish \frac{3\times 4+1}{4} ga k'paytirish \frac{2\times 2+1}{2} ga qaytarish.

$$3-\frac{\left(3\times 4+1\right)\times 2}{4\left(2\times 2+1\right)}+0\times 3$$

Surat va maxrajdagi ikkala 2 ni qisqartiring.

$$3-\frac{1+3\times 4}{2\left(1+2\times 2\right)}+0\times 3$$

12 hosil qilish uchun 3 va 4 ni ko'paytirish.

$$3-\frac{1+12}{2\left(1+2\times 2\right)}+0\times 3$$

13 olish uchun 1 va 12'ni qo'shing.

$$3-\frac{13}{2\left(1+2\times 2\right)}+0\times 3$$

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

$$3-\frac{13}{2\left(1+4\right)}+0\times 3$$

5 olish uchun 1 va 4'ni qo'shing.

$$3-\frac{13}{2\times 5}+0\times 3$$

10 hosil qilish uchun 2 va 5 ni ko'paytirish.

$$3-\frac{13}{10}+0\times 3$$

3 ni \frac{30}{10} kasrga o‘giring.

$$\frac{30}{10}-\frac{13}{10}+0\times 3$$

\frac{30}{10} va \frac{13}{10} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{30-13}{10}+0\times 3$$

17 olish uchun 30 dan 13 ni ayirish.

$$\frac{17}{10}+0\times 3$$

0 hosil qilish uchun 0 va 3 ni ko'paytirish.

$$\frac{17}{10}+0$$

\frac{17}{10} olish uchun \frac{17}{10} va 0'ni qo'shing.

$$\frac{17}{10}$$

Omil

$$\frac{17}{2 \cdot 5} = 1\frac{7}{10} = 1,7$$
