Yechim qadamlari

13 hosil qilish uchun 1 va 13 ni ko'paytirish.

$$\left(-\frac{13+11}{13}\right)\left(-\frac{2\times 16+7}{16}\right)$$

24 olish uchun 13 va 11'ni qo'shing.

$$-\frac{24}{13}\left(-\frac{2\times 16+7}{16}\right)$$

32 hosil qilish uchun 2 va 16 ni ko'paytirish.

$$-\frac{24}{13}\left(-\frac{32+7}{16}\right)$$

39 olish uchun 32 va 7'ni qo'shing.

$$-\frac{24}{13}\left(-\frac{39}{16}\right)$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{24}{13} ni -\frac{39}{16} ga ko‘paytiring.

$$\frac{-24\left(-39\right)}{13\times 16}$$

\frac{-24\left(-39\right)}{13\times 16} kasridagi ko‘paytirishlarni bajaring.

$$\frac{936}{208}$$

\frac{936}{208} ulushini 104 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
