Yechim qadamlari

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{13}{5} ni \frac{7}{26} ga ko‘paytiring.

$$\frac{13\times 7}{5\times 26}\times \frac{-50}{7}\times \frac{-1}{5}$$

\frac{13\times 7}{5\times 26} kasridagi ko‘paytirishlarni bajaring.

$$\frac{91}{130}\times \frac{-50}{7}\times \frac{-1}{5}$$

\frac{91}{130} ulushini 13 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{7}{10}\times \frac{-50}{7}\times \frac{-1}{5}$$

\frac{-50}{7} kasri manfiy belgini olib tashlash bilan -\frac{50}{7} sifatida qayta yozilishi mumkin.

$$\frac{7}{10}\left(-\frac{50}{7}\right)\times \frac{-1}{5}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{7}{10} ni -\frac{50}{7} ga ko‘paytiring.

$$\frac{7\left(-50\right)}{10\times 7}\times \frac{-1}{5}$$

Surat va maxrajdagi ikkala 7 ni qisqartiring.

$$\frac{-50}{10}\times \frac{-1}{5}$$
