Yechim qadamlari

\frac{4}{100} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$18-\frac{1}{25}-\frac{3}{100}-\frac{10}{100}-\frac{15}{100}$$

18 ni \frac{450}{25} kasrga o‘giring.

$$\frac{450}{25}-\frac{1}{25}-\frac{3}{100}-\frac{10}{100}-\frac{15}{100}$$

\frac{450}{25} va \frac{1}{25} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{450-1}{25}-\frac{3}{100}-\frac{10}{100}-\frac{15}{100}$$

449 olish uchun 450 dan 1 ni ayirish.

$$\frac{449}{25}-\frac{3}{100}-\frac{10}{100}-\frac{15}{100}$$

25 va 100 ning eng kichik umumiy karralisi 100 ga teng. \frac{449}{25} va \frac{3}{100} ni 100 maxraj bilan kasrlarga aylantirib oling.

$$\frac{1796}{100}-\frac{3}{100}-\frac{10}{100}-\frac{15}{100}$$

\frac{1796}{100} va \frac{3}{100} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{1796-3}{100}-\frac{10}{100}-\frac{15}{100}$$

1793 olish uchun 1796 dan 3 ni ayirish.

$$\frac{1793}{100}-\frac{10}{100}-\frac{15}{100}$$

\frac{1793}{100} va \frac{10}{100} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{1793-10}{100}-\frac{15}{100}$$

1783 olish uchun 1793 dan 10 ni ayirish.

$$\frac{1783}{100}-\frac{15}{100}$$
