$$1 \frac { 1 } { 12 } + 2 \frac { 2 } { 3 }$$

Baholash

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

Yechim qadamlari

12 hosil qilish uchun 1 va 12 ni ko'paytirish.

$$\frac{12+1}{12}+\frac{2\times 3+2}{3}$$

13 olish uchun 12 va 1'ni qo'shing.

$$\frac{13}{12}+\frac{2\times 3+2}{3}$$

6 hosil qilish uchun 2 va 3 ni ko'paytirish.

$$\frac{13}{12}+\frac{6+2}{3}$$

8 olish uchun 6 va 2'ni qo'shing.

$$\frac{13}{12}+\frac{8}{3}$$

12 va 3 ning eng kichik umumiy karralisi 12 ga teng. \frac{13}{12} va \frac{8}{3} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$\frac{13}{12}+\frac{32}{12}$$

\frac{13}{12} va \frac{32}{12} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{13+32}{12}$$

45 olish uchun 13 va 32'ni qo'shing.

$$\frac{45}{12}$$

\frac{45}{12} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

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

Omil

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