(-1/3-1/2)div5/4 eching

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

Baholash

$$-\frac{2}{3}\approx -0,666666667$$

Yechim qadamlari

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

$$\frac{-\frac{2}{6}-\frac{3}{6}}{\frac{5}{4}}$$

-\frac{2}{6} va \frac{3}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{\frac{-2-3}{6}}{\frac{5}{4}}$$

-5 olish uchun -2 dan 3 ni ayirish.

$$\frac{-\frac{5}{6}}{\frac{5}{4}}$$

-\frac{5}{6} ni \frac{5}{4} ga bo'lish -\frac{5}{6} ga k'paytirish \frac{5}{4} ga qaytarish.

$$-\frac{5}{6}\times \frac{4}{5}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{5}{6} ni \frac{4}{5} ga ko‘paytiring.

$$\frac{-5\times 4}{6\times 5}$$

\frac{-5\times 4}{6\times 5} kasridagi ko‘paytirishlarni bajaring.

$$\frac{-20}{30}$$

\frac{-20}{30} ulushini 10 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
