Yechim qadamlari

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{1}{2} ni \frac{19}{7} ga ko‘paytiring.

$$\frac{\frac{1\times 19}{2\times 7}}{\frac{2}{4}-\frac{1}{6}}+3$$

\frac{1\times 19}{2\times 7} kasridagi ko‘paytirishlarni bajaring.

$$\frac{\frac{19}{14}}{\frac{2}{4}-\frac{1}{6}}+3$$

\frac{2}{4} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{\frac{19}{14}}{\frac{1}{2}-\frac{1}{6}}+3$$

2 va 6 ning eng kichik umumiy karralisi 6 ga teng. \frac{1}{2} va \frac{1}{6} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$\frac{\frac{19}{14}}{\frac{3}{6}-\frac{1}{6}}+3$$

\frac{3}{6} va \frac{1}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{\frac{19}{14}}{\frac{3-1}{6}}+3$$

2 olish uchun 3 dan 1 ni ayirish.

$$\frac{\frac{19}{14}}{\frac{2}{6}}+3$$

\frac{2}{6} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

57 hosil qilish uchun 19 va 3 ni ko'paytirish.

$$\frac{57}{14}+3$$

3 ni \frac{42}{14} kasrga o‘giring.

$$\frac{57}{14}+\frac{42}{14}$$

\frac{57}{14} va \frac{42}{14} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{57+42}{14}$$

99 olish uchun 57 va 42'ni qo'shing.

$$\frac{99}{14}$$
