15div(-3/2+5/6) eching

$$15 \div ( - \frac { 3 } { 2 } + \frac { 5 } { 6 } )$$

Baholash

$$-\frac{45}{2}=-22,5$$

Yechim qadamlari

2 va 6 ning eng kichik umumiy karralisi 6 ga teng. -\frac{3}{2} va \frac{5}{6} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$\frac{15}{-\frac{9}{6}+\frac{5}{6}}$$

-\frac{9}{6} va \frac{5}{6} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{15}{\frac{-9+5}{6}}$$

-4 olish uchun -9 va 5'ni qo'shing.

$$\frac{15}{\frac{-4}{6}}$$

\frac{-4}{6} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{15}{-\frac{2}{3}}$$

15 ni -\frac{2}{3} ga bo'lish 15 ga k'paytirish -\frac{2}{3} ga qaytarish.

$$15\left(-\frac{3}{2}\right)$$

15\left(-\frac{3}{2}\right) ni yagona kasrga aylantiring.

$$\frac{15\left(-3\right)}{2}$$

-45 hosil qilish uchun 15 va -3 ni ko'paytirish.

$$\frac{-45}{2}$$

\frac{-45}{2} kasri manfiy belgini olib tashlash bilan -\frac{45}{2} sifatida qayta yozilishi mumkin.

$$-\frac{45}{2}$$

Omil

$$-\frac{45}{2} = -22\frac{1}{2} = -22,5$$
