41/2+32/10 eching

$$4 \frac { 1 } { 2 } + 3 \frac { 2 } { 10 }$$

Baholash

$$\frac{77}{10}=7,7$$

Yechim qadamlari

8 hosil qilish uchun 4 va 2 ni ko'paytirish.

$$\frac{8+1}{2}+\frac{3\times 10+2}{10}$$

9 olish uchun 8 va 1'ni qo'shing.

$$\frac{9}{2}+\frac{3\times 10+2}{10}$$

30 hosil qilish uchun 3 va 10 ni ko'paytirish.

$$\frac{9}{2}+\frac{30+2}{10}$$

32 olish uchun 30 va 2'ni qo'shing.

$$\frac{9}{2}+\frac{32}{10}$$

\frac{32}{10} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{9}{2}+\frac{16}{5}$$

2 va 5 ning eng kichik umumiy karralisi 10 ga teng. \frac{9}{2} va \frac{16}{5} ni 10 maxraj bilan kasrlarga aylantirib oling.

$$\frac{45}{10}+\frac{32}{10}$$

\frac{45}{10} va \frac{32}{10} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{45+32}{10}$$

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

$$\frac{77}{10}$$

Omil

$$\frac{7 \cdot 11}{2 \cdot 5} = 7\frac{7}{10} = 7,7$$
