Yechim qadamlari

4 va 12 ning eng kichik umumiy karralisi 12 ga teng. \frac{3}{4} va \frac{7}{12} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$\frac{9}{12}+\frac{7}{12}-\frac{7}{6}$$

\frac{9}{12} va \frac{7}{12} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{9+7}{12}-\frac{7}{6}$$

16 olish uchun 9 va 7'ni qo'shing.

$$\frac{16}{12}-\frac{7}{6}$$

\frac{16}{12} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{4}{3}-\frac{7}{6}$$

3 va 6 ning eng kichik umumiy karralisi 6 ga teng. \frac{4}{3} va \frac{7}{6} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$\frac{8}{6}-\frac{7}{6}$$

\frac{8}{6} va \frac{7}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{8-7}{6}$$

1 olish uchun 8 dan 7 ni ayirish.

$$\frac{1}{6}$$
