4/5-5(1/3)+3/2 eching

$$\frac{ 4 }{ 5 } -5( \frac{ 1 }{ 3 } )+ \frac{ 3 }{ 2 }$$

Baholash

$$\frac{19}{30}\approx 0,633333333$$

Yechim qadamlari

\frac{5}{3} hosil qilish uchun 5 va \frac{1}{3} ni ko'paytirish.

$$\frac{4}{5}-\frac{5}{3}+\frac{3}{2}$$

5 va 3 ning eng kichik umumiy karralisi 15 ga teng. \frac{4}{5} va \frac{5}{3} ni 15 maxraj bilan kasrlarga aylantirib oling.

$$\frac{12}{15}-\frac{25}{15}+\frac{3}{2}$$

\frac{12}{15} va \frac{25}{15} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{12-25}{15}+\frac{3}{2}$$

-13 olish uchun 12 dan 25 ni ayirish.

$$-\frac{13}{15}+\frac{3}{2}$$

15 va 2 ning eng kichik umumiy karralisi 30 ga teng. -\frac{13}{15} va \frac{3}{2} ni 30 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{26}{30}+\frac{45}{30}$$

-\frac{26}{30} va \frac{45}{30} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-26+45}{30}$$

19 olish uchun -26 va 45'ni qo'shing.

$$\frac{19}{30}$$

Omil

$$\frac{19}{2 \cdot 3 \cdot 5} = 0,6333333333333333$$
