13/10+14/5-11/4 eching

$$1 \frac { 3 } { 10 } + 1 \frac { 4 } { 5 } - 1 \frac { 1 } { 4 }$$

Baholash

$$\frac{37}{20}=1,85$$

Yechim qadamlari

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

$$\frac{10+3}{10}+\frac{1\times 5+4}{5}-\frac{1\times 4+1}{4}$$

13 olish uchun 10 va 3'ni qo'shing.

$$\frac{13}{10}+\frac{1\times 5+4}{5}-\frac{1\times 4+1}{4}$$

5 hosil qilish uchun 1 va 5 ni ko'paytirish.

$$\frac{13}{10}+\frac{5+4}{5}-\frac{1\times 4+1}{4}$$

9 olish uchun 5 va 4'ni qo'shing.

$$\frac{13}{10}+\frac{9}{5}-\frac{1\times 4+1}{4}$$

10 va 5 ning eng kichik umumiy karralisi 10 ga teng. \frac{13}{10} va \frac{9}{5} ni 10 maxraj bilan kasrlarga aylantirib oling.

$$\frac{13}{10}+\frac{18}{10}-\frac{1\times 4+1}{4}$$

\frac{13}{10} va \frac{18}{10} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{13+18}{10}-\frac{1\times 4+1}{4}$$

31 olish uchun 13 va 18'ni qo'shing.

$$\frac{31}{10}-\frac{1\times 4+1}{4}$$

4 hosil qilish uchun 1 va 4 ni ko'paytirish.

$$\frac{31}{10}-\frac{4+1}{4}$$

5 olish uchun 4 va 1'ni qo'shing.

$$\frac{31}{10}-\frac{5}{4}$$

10 va 4 ning eng kichik umumiy karralisi 20 ga teng. \frac{31}{10} va \frac{5}{4} ni 20 maxraj bilan kasrlarga aylantirib oling.

$$\frac{62}{20}-\frac{25}{20}$$

\frac{62}{20} va \frac{25}{20} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{62-25}{20}$$

37 olish uchun 62 dan 25 ni ayirish.

$$\frac{37}{20}$$

Omil

$$\frac{37}{2 ^ {2} \cdot 5} = 1\frac{17}{20} = 1,85$$
