4-3(4/3-3/2) eching

$$4 - 3 ( \frac { 4 } { 3 } - \frac { 3 } { 2 } )$$

Baholash

$$\frac{9}{2}=4,5$$

Yechim qadamlari

3 va 2 ning eng kichik umumiy karralisi 6 ga teng. \frac{4}{3} va \frac{3}{2} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$4-3\left(\frac{8}{6}-\frac{9}{6}\right)$$

\frac{8}{6} va \frac{9}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$4-3\times \frac{8-9}{6}$$

-1 olish uchun 8 dan 9 ni ayirish.

$$4-3\left(-\frac{1}{6}\right)$$

3\left(-\frac{1}{6}\right) ni yagona kasrga aylantiring.

$$4-\frac{3\left(-1\right)}{6}$$

-3 hosil qilish uchun 3 va -1 ni ko'paytirish.

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

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

$$4-\left(-\frac{1}{2}\right)$$

-\frac{1}{2} ning teskarisi \frac{1}{2} ga teng.

$$4+\frac{1}{2}$$

4 ni \frac{8}{2} kasrga o‘giring.

$$\frac{8}{2}+\frac{1}{2}$$

\frac{8}{2} va \frac{1}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{8+1}{2}$$

9 olish uchun 8 va 1'ni qo'shing.

$$\frac{9}{2}$$

Omil

$$\frac{3 ^ {2}}{2} = 4\frac{1}{2} = 4,5$$
