3:2*6/2+6-12/3*5/8= eching

$$3 : \frac { 2 \cdot 6 } { 2 + 6 } - \frac { 12 } { 3 } \cdot \frac { 5 } { 8 } =$$

Baholash

$$-\frac{1}{2}=-0,5$$

Yechim qadamlari

3 ni \frac{2\times 6}{2+6} ga bo'lish 3 ga k'paytirish \frac{2\times 6}{2+6} ga qaytarish.

$$\frac{3\left(2+6\right)}{2\times 6}-\frac{12}{3}\times \frac{5}{8}$$

Surat va maxrajdagi ikkala 3 ni qisqartiring.

$$\frac{2+6}{2\times 2}-\frac{12}{3}\times \frac{5}{8}$$

8 olish uchun 2 va 6'ni qo'shing.

$$\frac{8}{2\times 2}-\frac{12}{3}\times \frac{5}{8}$$

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

$$\frac{8}{4}-\frac{12}{3}\times \frac{5}{8}$$

2 ni olish uchun 8 ni 4 ga bo‘ling.

$$2-\frac{12}{3}\times \frac{5}{8}$$

4 ni olish uchun 12 ni 3 ga bo‘ling.

$$2-4\times \frac{5}{8}$$

4\times \frac{5}{8} ni yagona kasrga aylantiring.

$$2-\frac{4\times 5}{8}$$

20 hosil qilish uchun 4 va 5 ni ko'paytirish.

$$2-\frac{20}{8}$$

\frac{20}{8} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$2-\frac{5}{2}$$

2 ni \frac{4}{2} kasrga o‘giring.

$$\frac{4}{2}-\frac{5}{2}$$

\frac{4}{2} va \frac{5}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{4-5}{2}$$

-1 olish uchun 4 dan 5 ni ayirish.

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

Omil

$$-\frac{1}{2} = -0,5$$
