4div8/3-3/5 eching

$$4 \div \frac { 8 } { 3 } - \frac { 3 } { 5 }$$

Baholash

$$\frac{9}{10}=0,9$$

Yechim qadamlari

4 ni \frac{8}{3} ga bo'lish 4 ga k'paytirish \frac{8}{3} ga qaytarish.

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

4\times \frac{3}{8} ni yagona kasrga aylantiring.

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

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

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

\frac{12}{8} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

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

2 va 5 ning eng kichik umumiy karralisi 10 ga teng. \frac{3}{2} va \frac{3}{5} ni 10 maxraj bilan kasrlarga aylantirib oling.

$$\frac{15}{10}-\frac{6}{10}$$

\frac{15}{10} va \frac{6}{10} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{15-6}{10}$$

9 olish uchun 15 dan 6 ni ayirish.

$$\frac{9}{10}$$

Omil

$$\frac{3 ^ {2}}{2 \cdot 5} = 0,9$$
