$$4 \frac { 2 } { 3 } - 3 \frac { 1 } { 9 } =$$

Baholash

$$\frac{14}{9}\approx 1,555555556$$

Yechim qadamlari

12 hosil qilish uchun 4 va 3 ni ko'paytirish.

$$\frac{12+2}{3}-\frac{3\times 9+1}{9}$$

14 olish uchun 12 va 2'ni qo'shing.

$$\frac{14}{3}-\frac{3\times 9+1}{9}$$

27 hosil qilish uchun 3 va 9 ni ko'paytirish.

$$\frac{14}{3}-\frac{27+1}{9}$$

28 olish uchun 27 va 1'ni qo'shing.

$$\frac{14}{3}-\frac{28}{9}$$

3 va 9 ning eng kichik umumiy karralisi 9 ga teng. \frac{14}{3} va \frac{28}{9} ni 9 maxraj bilan kasrlarga aylantirib oling.

$$\frac{42}{9}-\frac{28}{9}$$

\frac{42}{9} va \frac{28}{9} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{42-28}{9}$$

14 olish uchun 42 dan 28 ni ayirish.

$$\frac{14}{9}$$

Omil

$$\frac{2 \cdot 7}{3 ^ {2}} = 1\frac{5}{9} = 1,5555555555555556$$
