Yechim qadamlari

9 hosil qilish uchun 3 va 3 ni ko'paytirish.

$$\frac{\frac{1}{4}\left(-\frac{9+1}{3}\right)}{\frac{1\times 7+3}{7}}$$

10 olish uchun 9 va 1'ni qo'shing.

$$\frac{\frac{1}{4}\left(-\frac{10}{3}\right)}{\frac{1\times 7+3}{7}}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{1}{4} ni -\frac{10}{3} ga ko‘paytiring.

$$\frac{\frac{1\left(-10\right)}{4\times 3}}{\frac{1\times 7+3}{7}}$$

\frac{1\left(-10\right)}{4\times 3} kasridagi ko‘paytirishlarni bajaring.

$$\frac{\frac{-10}{12}}{\frac{1\times 7+3}{7}}$$

\frac{-10}{12} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{-\frac{5}{6}}{\frac{1\times 7+3}{7}}$$

7 hosil qilish uchun 1 va 7 ni ko'paytirish.

$$\frac{-\frac{5}{6}}{\frac{7+3}{7}}$$

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

$$\frac{-\frac{5}{6}}{\frac{10}{7}}$$

-\frac{5}{6} ni \frac{10}{7} ga bo'lish -\frac{5}{6} ga k'paytirish \frac{10}{7} ga qaytarish.

$$-\frac{5}{6}\times \frac{7}{10}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{5}{6} ni \frac{7}{10} ga ko‘paytiring.

$$\frac{-5\times 7}{6\times 10}$$

\frac{-5\times 7}{6\times 10} kasridagi ko‘paytirishlarni bajaring.

$$\frac{-35}{60}$$

\frac{-35}{60} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{7}{12}$$
