Yechim qadamlari

1 ni olish uchun 2 ni 2 ga bo‘ling.

$$\frac{\frac{7}{4}-1}{\frac{4}{5}-\frac{3}{2}}$$

1 ni \frac{4}{4} kasrga o‘giring.

$$\frac{\frac{7}{4}-\frac{4}{4}}{\frac{4}{5}-\frac{3}{2}}$$

\frac{7}{4} va \frac{4}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{\frac{7-4}{4}}{\frac{4}{5}-\frac{3}{2}}$$

3 olish uchun 7 dan 4 ni ayirish.

$$\frac{\frac{3}{4}}{\frac{4}{5}-\frac{3}{2}}$$

5 va 2 ning eng kichik umumiy karralisi 10 ga teng. \frac{4}{5} va \frac{3}{2} ni 10 maxraj bilan kasrlarga aylantirib oling.

$$\frac{\frac{3}{4}}{\frac{8}{10}-\frac{15}{10}}$$

\frac{8}{10} va \frac{15}{10} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{\frac{3}{4}}{\frac{8-15}{10}}$$

-7 olish uchun 8 dan 15 ni ayirish.

$$\frac{\frac{3}{4}}{-\frac{7}{10}}$$

\frac{3}{4} ni -\frac{7}{10} ga bo'lish \frac{3}{4} ga k'paytirish -\frac{7}{10} ga qaytarish.

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

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{3}{4} ni -\frac{10}{7} ga ko‘paytiring.

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

\frac{3\left(-10\right)}{4\times 7} kasridagi ko‘paytirishlarni bajaring.

$$\frac{-30}{28}$$

\frac{-30}{28} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{15}{14}$$
