(1/2-4/3)*3/5 eching

$$( \frac { 1 } { 2 } - \frac { 4 } { 3 } ) \cdot \frac { 3 } { 5 }$$

Baholash

$$-\frac{1}{2}=-0,5$$

Yechim qadamlari

2 va 3 ning eng kichik umumiy karralisi 6 ga teng. \frac{1}{2} va \frac{4}{3} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$\left(\frac{3}{6}-\frac{8}{6}\right)\times \frac{3}{5}$$

\frac{3}{6} va \frac{8}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{3-8}{6}\times \frac{3}{5}$$

-5 olish uchun 3 dan 8 ni ayirish.

$$-\frac{5}{6}\times \frac{3}{5}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{5}{6} ni \frac{3}{5} ga ko‘paytiring.

$$\frac{-5\times 3}{6\times 5}$$

\frac{-5\times 3}{6\times 5} kasridagi ko‘paytirishlarni bajaring.

$$\frac{-15}{30}$$

\frac{-15}{30} ulushini 15 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{1}{2}$$

Omil

$$-\frac{1}{2} = -0,5$$
