15/10+16/10= eching

$$1 \frac { 5 } { 10 } + 1 \frac { 6 } { 10 } =$$

Baholash

$$\frac{31}{10}=3,1$$

Yechim qadamlari

10 hosil qilish uchun 1 va 10 ni ko'paytirish.

$$\frac{10+5}{10}+\frac{1\times 10+6}{10}$$

15 olish uchun 10 va 5'ni qo'shing.

$$\frac{15}{10}+\frac{1\times 10+6}{10}$$

\frac{15}{10} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{3}{2}+\frac{1\times 10+6}{10}$$

10 hosil qilish uchun 1 va 10 ni ko'paytirish.

$$\frac{3}{2}+\frac{10+6}{10}$$

16 olish uchun 10 va 6'ni qo'shing.

$$\frac{3}{2}+\frac{16}{10}$$

\frac{16}{10} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{3}{2}+\frac{8}{5}$$

2 va 5 ning eng kichik umumiy karralisi 10 ga teng. \frac{3}{2} va \frac{8}{5} ni 10 maxraj bilan kasrlarga aylantirib oling.

$$\frac{15}{10}+\frac{16}{10}$$

\frac{15}{10} va \frac{16}{10} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{15+16}{10}$$

31 olish uchun 15 va 16'ni qo'shing.

$$\frac{31}{10}$$

Omil

$$\frac{31}{2 \cdot 5} = 3\frac{1}{10} = 3,1$$
