Yechim qadamlari

41 ni \frac{82}{2} kasrga o‘giring.

$$\frac{1}{2}+\frac{82}{2}-\frac{1}{4}-101+7$$

\frac{1}{2} va \frac{82}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{1+82}{2}-\frac{1}{4}-101+7$$

83 olish uchun 1 va 82'ni qo'shing.

$$\frac{83}{2}-\frac{1}{4}-101+7$$

2 va 4 ning eng kichik umumiy karralisi 4 ga teng. \frac{83}{2} va \frac{1}{4} ni 4 maxraj bilan kasrlarga aylantirib oling.

$$\frac{166}{4}-\frac{1}{4}-101+7$$

\frac{166}{4} va \frac{1}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{166-1}{4}-101+7$$

165 olish uchun 166 dan 1 ni ayirish.

$$\frac{165}{4}-101+7$$

101 ni \frac{404}{4} kasrga o‘giring.

$$\frac{165}{4}-\frac{404}{4}+7$$

\frac{165}{4} va \frac{404}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{165-404}{4}+7$$

-239 olish uchun 165 dan 404 ni ayirish.

$$-\frac{239}{4}+7$$

7 ni \frac{28}{4} kasrga o‘giring.

$$-\frac{239}{4}+\frac{28}{4}$$

-\frac{239}{4} va \frac{28}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-239+28}{4}$$

-211 olish uchun -239 va 28'ni qo'shing.

$$-\frac{211}{4}$$

Omil

$$-\frac{211}{4} = -52\frac{3}{4} = -52,75$$
