203/4-182/3 eching

$$20 \frac { 3 } { 4 } - 18 \frac { 2 } { 3 }$$

Baholash

$$\frac{25}{12}\approx 2,083333333$$

Yechim qadamlari

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

$$\frac{80+3}{4}-\frac{18\times 3+2}{3}$$

83 olish uchun 80 va 3'ni qo'shing.

$$\frac{83}{4}-\frac{18\times 3+2}{3}$$

54 hosil qilish uchun 18 va 3 ni ko'paytirish.

$$\frac{83}{4}-\frac{54+2}{3}$$

56 olish uchun 54 va 2'ni qo'shing.

$$\frac{83}{4}-\frac{56}{3}$$

4 va 3 ning eng kichik umumiy karralisi 12 ga teng. \frac{83}{4} va \frac{56}{3} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$\frac{249}{12}-\frac{224}{12}$$

\frac{249}{12} va \frac{224}{12} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{249-224}{12}$$

25 olish uchun 249 dan 224 ni ayirish.

$$\frac{25}{12}$$

Omil

$$\frac{5 ^ {2}}{2 ^ {2} \cdot 3} = 2\frac{1}{12} = 2,0833333333333335$$
