41/2+53/5 eching

$$4 \frac { 1 } { 2 } + 5 \frac { 3 } { 5 }$$

Baholash

$$\frac{101}{10}=10,1$$

Yechim qadamlari

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

$$\frac{8+1}{2}+\frac{5\times 5+3}{5}$$

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

$$\frac{9}{2}+\frac{5\times 5+3}{5}$$

25 hosil qilish uchun 5 va 5 ni ko'paytirish.

$$\frac{9}{2}+\frac{25+3}{5}$$

28 olish uchun 25 va 3'ni qo'shing.

$$\frac{9}{2}+\frac{28}{5}$$

2 va 5 ning eng kichik umumiy karralisi 10 ga teng. \frac{9}{2} va \frac{28}{5} ni 10 maxraj bilan kasrlarga aylantirib oling.

$$\frac{45}{10}+\frac{56}{10}$$

\frac{45}{10} va \frac{56}{10} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{45+56}{10}$$

101 olish uchun 45 va 56'ni qo'shing.

$$\frac{101}{10}$$

Omil

$$\frac{101}{2 \cdot 5} = 10\frac{1}{10} = 10,1$$
