Yechim qadamlari

18 va 24 ning eng kichik umumiy karralisi 72 ga teng. \frac{1}{18} va \frac{1}{24} ni 72 maxraj bilan kasrlarga aylantirib oling.

$$\frac{4}{72}+\frac{3}{72}+\frac{1}{36}$$

\frac{4}{72} va \frac{3}{72} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{4+3}{72}+\frac{1}{36}$$

7 olish uchun 4 va 3'ni qo'shing.

$$\frac{7}{72}+\frac{1}{36}$$

72 va 36 ning eng kichik umumiy karralisi 72 ga teng. \frac{7}{72} va \frac{1}{36} ni 72 maxraj bilan kasrlarga aylantirib oling.

$$\frac{7}{72}+\frac{2}{72}$$

\frac{7}{72} va \frac{2}{72} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{7+2}{72}$$

9 olish uchun 7 va 2'ni qo'shing.

$$\frac{9}{72}$$

\frac{9}{72} ulushini 9 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
