Yechim qadamlari

49 olish uchun 20 va 29'ni qo'shing.

$$\frac{49}{\frac{20}{30}+\frac{29}{40}}$$

\frac{20}{30} ulushini 10 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{49}{\frac{2}{3}+\frac{29}{40}}$$

3 va 40 ning eng kichik umumiy karralisi 120 ga teng. \frac{2}{3} va \frac{29}{40} ni 120 maxraj bilan kasrlarga aylantirib oling.

$$\frac{49}{\frac{80}{120}+\frac{87}{120}}$$

\frac{80}{120} va \frac{87}{120} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{49}{\frac{80+87}{120}}$$

167 olish uchun 80 va 87'ni qo'shing.

$$\frac{49}{\frac{167}{120}}$$

49 ni \frac{167}{120} ga bo'lish 49 ga k'paytirish \frac{167}{120} ga qaytarish.

$$49\times \frac{120}{167}$$

49\times \frac{120}{167} ni yagona kasrga aylantiring.

$$\frac{49\times 120}{167}$$

5880 hosil qilish uchun 49 va 120 ni ko'paytirish.

$$\frac{5880}{167}$$
