2/3+5/6+23/12 eching

$$\frac { 2 } { 3 } + \frac { 5 } { 6 } + 2 \frac { 3 } { 12 }$$

Baholash

$$\frac{15}{4}=3,75$$

Yechim qadamlari

3 va 6 ning eng kichik umumiy karralisi 6 ga teng. \frac{2}{3} va \frac{5}{6} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$\frac{4}{6}+\frac{5}{6}+\frac{2\times 12+3}{12}$$

\frac{4}{6} va \frac{5}{6} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{4+5}{6}+\frac{2\times 12+3}{12}$$

9 olish uchun 4 va 5'ni qo'shing.

$$\frac{9}{6}+\frac{2\times 12+3}{12}$$

\frac{9}{6} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{3}{2}+\frac{2\times 12+3}{12}$$

24 hosil qilish uchun 2 va 12 ni ko'paytirish.

$$\frac{3}{2}+\frac{24+3}{12}$$

27 olish uchun 24 va 3'ni qo'shing.

$$\frac{3}{2}+\frac{27}{12}$$

\frac{27}{12} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{3}{2}+\frac{9}{4}$$

2 va 4 ning eng kichik umumiy karralisi 4 ga teng. \frac{3}{2} va \frac{9}{4} ni 4 maxraj bilan kasrlarga aylantirib oling.

$$\frac{6}{4}+\frac{9}{4}$$

\frac{6}{4} va \frac{9}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{6+9}{4}$$

15 olish uchun 6 va 9'ni qo'shing.

$$\frac{15}{4}$$

Omil

$$\frac{3 \cdot 5}{2 ^ {2}} = 3\frac{3}{4} = 3,75$$
