2(36/6)+2(7/10) eching

$$2( 3 \frac { 6 } { 6 } )+2( \frac{ 7 }{ 10 } )$$

Baholash

$$\frac{47}{5}=9,4$$

Yechim qadamlari

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

$$2\times \frac{18+6}{6}+2\times \frac{7}{10}$$

24 olish uchun 18 va 6'ni qo'shing.

$$2\times \frac{24}{6}+2\times \frac{7}{10}$$

4 ni olish uchun 24 ni 6 ga bo‘ling.

$$2\times 4+2\times \frac{7}{10}$$

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

$$8+2\times \frac{7}{10}$$

2\times \frac{7}{10} ni yagona kasrga aylantiring.

$$8+\frac{2\times 7}{10}$$

14 hosil qilish uchun 2 va 7 ni ko'paytirish.

$$8+\frac{14}{10}$$

\frac{14}{10} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$8+\frac{7}{5}$$

8 ni \frac{40}{5} kasrga o‘giring.

$$\frac{40}{5}+\frac{7}{5}$$

\frac{40}{5} va \frac{7}{5} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{40+7}{5}$$

47 olish uchun 40 va 7'ni qo'shing.

$$\frac{47}{5}$$

Omil

$$\frac{47}{5} = 9\frac{2}{5} = 9,4$$
