42/3-11/6 eching

$$4 \frac { 2 } { 3 } - 1 \frac { 1 } { 6 }$$

Baholash

$$\frac{7}{2}=3,5$$

Yechim qadamlari

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

$$\frac{12+2}{3}-\frac{1\times 6+1}{6}$$

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

$$\frac{14}{3}-\frac{1\times 6+1}{6}$$

6 hosil qilish uchun 1 va 6 ni ko'paytirish.

$$\frac{14}{3}-\frac{6+1}{6}$$

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

$$\frac{14}{3}-\frac{7}{6}$$

3 va 6 ning eng kichik umumiy karralisi 6 ga teng. \frac{14}{3} va \frac{7}{6} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$\frac{28}{6}-\frac{7}{6}$$

\frac{28}{6} va \frac{7}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{28-7}{6}$$

21 olish uchun 28 dan 7 ni ayirish.

$$\frac{21}{6}$$

\frac{21}{6} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{7}{2}$$

Omil

$$\frac{7}{2} = 3\frac{1}{2} = 3,5$$
