73/4-21/3 eching

$$7 \frac { 3 } { 4 } - 2 \frac { 1 } { 3 }$$

Baholash

$$\frac{65}{12}\approx 5,416666667$$

Yechim qadamlari

28 hosil qilish uchun 7 va 4 ni ko'paytirish.

$$\frac{28+3}{4}-\frac{2\times 3+1}{3}$$

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

$$\frac{31}{4}-\frac{2\times 3+1}{3}$$

6 hosil qilish uchun 2 va 3 ni ko'paytirish.

$$\frac{31}{4}-\frac{6+1}{3}$$

7 olish uchun 6 va 1'ni qo'shing.

$$\frac{31}{4}-\frac{7}{3}$$

4 va 3 ning eng kichik umumiy karralisi 12 ga teng. \frac{31}{4} va \frac{7}{3} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$\frac{93}{12}-\frac{28}{12}$$

\frac{93}{12} va \frac{28}{12} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{93-28}{12}$$

65 olish uchun 93 dan 28 ni ayirish.

$$\frac{65}{12}$$

Omil

$$\frac{5 \cdot 13}{2 ^ {2} \cdot 3} = 5\frac{5}{12} = 5,416666666666667$$
