(-025)*(-55)+1/4*(-35)-(-1/4)*2 eching

$$( - 025 ) \times ( - 55 ) + \frac { 1 } { 4 } \times ( - 35 ) - ( - \frac { 1 } { 4 } ) \times 2$$

Baholash

$$-\frac{33}{4}=-8,25$$

Yechim qadamlari

0 hosil qilish uchun 0 va 25 ni ko'paytirish.

$$0\left(-55\right)+\frac{1}{4}\left(-35\right)-\left(-\frac{1}{4}\times 2\right)$$

0 hosil qilish uchun 0 va -55 ni ko'paytirish.

$$0+\frac{1}{4}\left(-35\right)-\left(-\frac{1}{4}\times 2\right)$$

\frac{-35}{4} hosil qilish uchun \frac{1}{4} va -35 ni ko'paytirish.

$$0+\frac{-35}{4}-\left(-\frac{1}{4}\times 2\right)$$

\frac{-35}{4} kasri manfiy belgini olib tashlash bilan -\frac{35}{4} sifatida qayta yozilishi mumkin.

$$0-\frac{35}{4}-\left(-\frac{1}{4}\times 2\right)$$

-\frac{35}{4} olish uchun 0 dan \frac{35}{4} ni ayirish.

$$-\frac{35}{4}-\left(-\frac{1}{4}\times 2\right)$$

-\frac{1}{4}\times 2 ni yagona kasrga aylantiring.

$$-\frac{35}{4}-\frac{-2}{4}$$

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

$$-\frac{35}{4}-\left(-\frac{1}{2}\right)$$

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

$$-\frac{35}{4}+\frac{1}{2}$$

4 va 2 ning eng kichik umumiy karralisi 4 ga teng. -\frac{35}{4} va \frac{1}{2} ni 4 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{35}{4}+\frac{2}{4}$$

-\frac{35}{4} va \frac{2}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-35+2}{4}$$

-33 olish uchun -35 va 2'ni qo'shing.

$$-\frac{33}{4}$$

Omil

$$-\frac{33}{4} = -8\frac{1}{4} = -8,25$$
