13/11-(-1/2-5/11) eching

$$\frac { 13 } { 11 } - ( - \frac { 1 } { 2 } - \frac { 5 } { 11 } )$$

Baholash

$$\frac{47}{22}\approx 2,136363636$$

Yechim qadamlari

2 va 11 ning eng kichik umumiy karralisi 22 ga teng. -\frac{1}{2} va \frac{5}{11} ni 22 maxraj bilan kasrlarga aylantirib oling.

$$\frac{13}{11}-\left(-\frac{11}{22}-\frac{10}{22}\right)$$

-\frac{11}{22} va \frac{10}{22} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{13}{11}-\frac{-11-10}{22}$$

-21 olish uchun -11 dan 10 ni ayirish.

$$\frac{13}{11}-\left(-\frac{21}{22}\right)$$

-\frac{21}{22} ning teskarisi \frac{21}{22} ga teng.

$$\frac{13}{11}+\frac{21}{22}$$

11 va 22 ning eng kichik umumiy karralisi 22 ga teng. \frac{13}{11} va \frac{21}{22} ni 22 maxraj bilan kasrlarga aylantirib oling.

$$\frac{26}{22}+\frac{21}{22}$$

\frac{26}{22} va \frac{21}{22} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{26+21}{22}$$

47 olish uchun 26 va 21'ni qo'shing.

$$\frac{47}{22}$$

Omil

$$\frac{47}{2 \cdot 11} = 2\frac{3}{22} = 2,1363636363636362$$
