Yechim qadamlari

3 va 4 ning eng kichik umumiy karralisi 12 ga teng. \frac{1}{3} va \frac{1}{4} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$1-\left(\frac{4}{12}+\frac{3}{12}+\frac{1}{6}\right)$$

\frac{4}{12} va \frac{3}{12} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$1-\left(\frac{4+3}{12}+\frac{1}{6}\right)$$

7 olish uchun 4 va 3'ni qo'shing.

$$1-\left(\frac{7}{12}+\frac{1}{6}\right)$$

12 va 6 ning eng kichik umumiy karralisi 12 ga teng. \frac{7}{12} va \frac{1}{6} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$1-\left(\frac{7}{12}+\frac{2}{12}\right)$$

\frac{7}{12} va \frac{2}{12} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$1-\frac{7+2}{12}$$

9 olish uchun 7 va 2'ni qo'shing.

$$1-\frac{9}{12}$$

\frac{9}{12} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$1-\frac{3}{4}$$

1 ni \frac{4}{4} kasrga o‘giring.

$$\frac{4}{4}-\frac{3}{4}$$

\frac{4}{4} va \frac{3}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{4-3}{4}$$

1 olish uchun 4 dan 3 ni ayirish.

$$\frac{1}{4}$$
