2(154+3)/3-(154-3)/4 eching

$$\frac { 2 ( 154 + 3 ) } { 3 } - \frac { ( 154 - 3 ) } { 4 }$$

Baholash

$$\frac{803}{12}\approx 66,916666667$$

Yechim qadamlari

157 olish uchun 154 va 3'ni qo'shing.

$$\frac{2\times 157}{3}-\frac{154-3}{4}$$

314 hosil qilish uchun 2 va 157 ni ko'paytirish.

$$\frac{314}{3}-\frac{154-3}{4}$$

151 olish uchun 154 dan 3 ni ayirish.

$$\frac{314}{3}-\frac{151}{4}$$

3 va 4 ning eng kichik umumiy karralisi 12 ga teng. \frac{314}{3} va \frac{151}{4} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$\frac{1256}{12}-\frac{453}{12}$$

\frac{1256}{12} va \frac{453}{12} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{1256-453}{12}$$

803 olish uchun 1256 dan 453 ni ayirish.

$$\frac{803}{12}$$

Omil

$$\frac{11 \cdot 73}{2 ^ {2} \cdot 3} = 66\frac{11}{12} = 66,91666666666667$$
