Yechim qadamlari

\frac{5}{10} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{1}{2}+\frac{1}{100}+\frac{8}{1000}$$

2 va 100 ning eng kichik umumiy karralisi 100 ga teng. \frac{1}{2} va \frac{1}{100} ni 100 maxraj bilan kasrlarga aylantirib oling.

$$\frac{50}{100}+\frac{1}{100}+\frac{8}{1000}$$

\frac{50}{100} va \frac{1}{100} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{50+1}{100}+\frac{8}{1000}$$

51 olish uchun 50 va 1'ni qo'shing.

$$\frac{51}{100}+\frac{8}{1000}$$

\frac{8}{1000} ulushini 8 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{51}{100}+\frac{1}{125}$$

100 va 125 ning eng kichik umumiy karralisi 500 ga teng. \frac{51}{100} va \frac{1}{125} ni 500 maxraj bilan kasrlarga aylantirib oling.

$$\frac{255}{500}+\frac{4}{500}$$

\frac{255}{500} va \frac{4}{500} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{255+4}{500}$$

259 olish uchun 255 va 4'ni qo'shing.

$$\frac{259}{500}$$
