5/8+1/5+3/8 eching

$$\frac { 5 } { 8 } + \frac { 1 } { 5 } + \frac { 3 } { 8 }$$

Baholash

$$\frac{6}{5}=1,2$$

Yechim qadamlari

8 va 5 ning eng kichik umumiy karralisi 40 ga teng. \frac{5}{8} va \frac{1}{5} ni 40 maxraj bilan kasrlarga aylantirib oling.

$$\frac{25}{40}+\frac{8}{40}+\frac{3}{8}$$

\frac{25}{40} va \frac{8}{40} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{25+8}{40}+\frac{3}{8}$$

33 olish uchun 25 va 8'ni qo'shing.

$$\frac{33}{40}+\frac{3}{8}$$

40 va 8 ning eng kichik umumiy karralisi 40 ga teng. \frac{33}{40} va \frac{3}{8} ni 40 maxraj bilan kasrlarga aylantirib oling.

$$\frac{33}{40}+\frac{15}{40}$$

\frac{33}{40} va \frac{15}{40} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{33+15}{40}$$

48 olish uchun 33 va 15'ni qo'shing.

$$\frac{48}{40}$$

\frac{48}{40} ulushini 8 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{6}{5}$$

Omil

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