Yechim qadamlari

6 va 19 ning eng kichik umumiy karralisi 114 ga teng. \frac{5}{6} va \frac{7}{19} ni 114 maxraj bilan kasrlarga aylantirib oling.

$$\frac{95}{114}+\frac{42}{114}+\frac{12}{19}$$

\frac{95}{114} va \frac{42}{114} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{95+42}{114}+\frac{12}{19}$$

137 olish uchun 95 va 42'ni qo'shing.

$$\frac{137}{114}+\frac{12}{19}$$

114 va 19 ning eng kichik umumiy karralisi 114 ga teng. \frac{137}{114} va \frac{12}{19} ni 114 maxraj bilan kasrlarga aylantirib oling.

$$\frac{137}{114}+\frac{72}{114}$$

\frac{137}{114} va \frac{72}{114} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{137+72}{114}$$

209 olish uchun 137 va 72'ni qo'shing.

$$\frac{209}{114}$$

\frac{209}{114} ulushini 19 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
