Yechim qadamlari

98 va 49 ning eng kichik umumiy karralisi 98 ga teng. \frac{9}{98} va \frac{6}{49} ni 98 maxraj bilan kasrlarga aylantirib oling.

$$\frac{9}{98}+\frac{12}{98}+5$$

\frac{9}{98} va \frac{12}{98} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{9+12}{98}+5$$

21 olish uchun 9 va 12'ni qo'shing.

$$\frac{21}{98}+5$$

\frac{21}{98} ulushini 7 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{3}{14}+5$$

5 ni \frac{70}{14} kasrga o‘giring.

$$\frac{3}{14}+\frac{70}{14}$$

\frac{3}{14} va \frac{70}{14} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{3+70}{14}$$

73 olish uchun 3 va 70'ni qo'shing.

$$\frac{73}{14}$$
