(-13/4+7/8-7/12)*(-11/7) eching

$$( - 1 \frac { 3 } { 4 } + \frac { 7 } { 8 } - \frac { 7 } { 12 } ) \times ( - 1 \frac { 1 } { 7 } )$$

Baholash

$$\frac{5}{3}\approx 1,666666667$$

Yechim qadamlari

4 hosil qilish uchun 1 va 4 ni ko'paytirish.

$$\left(-\frac{4+3}{4}+\frac{7}{8}-\frac{7}{12}\right)\left(-\frac{1\times 7+1}{7}\right)$$

7 olish uchun 4 va 3'ni qo'shing.

$$\left(-\frac{7}{4}+\frac{7}{8}-\frac{7}{12}\right)\left(-\frac{1\times 7+1}{7}\right)$$

4 va 8 ning eng kichik umumiy karralisi 8 ga teng. -\frac{7}{4} va \frac{7}{8} ni 8 maxraj bilan kasrlarga aylantirib oling.

$$\left(-\frac{14}{8}+\frac{7}{8}-\frac{7}{12}\right)\left(-\frac{1\times 7+1}{7}\right)$$

-\frac{14}{8} va \frac{7}{8} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\left(\frac{-14+7}{8}-\frac{7}{12}\right)\left(-\frac{1\times 7+1}{7}\right)$$

-7 olish uchun -14 va 7'ni qo'shing.

$$\left(-\frac{7}{8}-\frac{7}{12}\right)\left(-\frac{1\times 7+1}{7}\right)$$

8 va 12 ning eng kichik umumiy karralisi 24 ga teng. -\frac{7}{8} va \frac{7}{12} ni 24 maxraj bilan kasrlarga aylantirib oling.

$$\left(-\frac{21}{24}-\frac{14}{24}\right)\left(-\frac{1\times 7+1}{7}\right)$$

-\frac{21}{24} va \frac{14}{24} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-21-14}{24}\left(-\frac{1\times 7+1}{7}\right)$$

-35 olish uchun -21 dan 14 ni ayirish.

$$-\frac{35}{24}\left(-\frac{7+1}{7}\right)$$

8 olish uchun 7 va 1'ni qo'shing.

$$-\frac{35}{24}\left(-\frac{8}{7}\right)$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{35}{24} ni -\frac{8}{7} ga ko‘paytiring.

$$\frac{-35\left(-8\right)}{24\times 7}$$

\frac{-35\left(-8\right)}{24\times 7} kasridagi ko‘paytirishlarni bajaring.

$$\frac{280}{168}$$

\frac{280}{168} ulushini 56 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{5}{3}$$

Omil

$$\frac{5}{3} = 1\frac{2}{3} = 1,6666666666666667$$
