A=3/7+1/7*(5+1/2) eching

$$A = \frac { 3 } { 7 } + \frac { 1 } { 7 } \times ( 5 + \frac { 1 } { 2 } )$$

A uchun yechish

$$A = \frac{17}{14} = 1\frac{3}{14} \approx 1,214285714$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

5 ni \frac{10}{2} kasrga o‘giring.

$$A=\frac{3}{7}+\frac{1}{7}\left(\frac{10}{2}+\frac{1}{2}\right)$$

\frac{10}{2} va \frac{1}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$A=\frac{3}{7}+\frac{1}{7}\times \frac{10+1}{2}$$

11 olish uchun 10 va 1'ni qo'shing.

$$A=\frac{3}{7}+\frac{1}{7}\times \frac{11}{2}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{1}{7} ni \frac{11}{2} ga ko‘paytiring.

$$A=\frac{3}{7}+\frac{1\times 11}{7\times 2}$$

\frac{1\times 11}{7\times 2} kasridagi ko‘paytirishlarni bajaring.

$$A=\frac{3}{7}+\frac{11}{14}$$

7 va 14 ning eng kichik umumiy karralisi 14 ga teng. \frac{3}{7} va \frac{11}{14} ni 14 maxraj bilan kasrlarga aylantirib oling.

$$A=\frac{6}{14}+\frac{11}{14}$$

\frac{6}{14} va \frac{11}{14} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$A=\frac{6+11}{14}$$

17 olish uchun 6 va 11'ni qo'shing.

$$A=\frac{17}{14}$$

A'ni tayinlash

$$A≔\frac{17}{14}$$
