Yechim qadamlari

3 ni olish uchun -45 ni -15 ga bo‘ling.

$$3+\frac{144}{64}-\frac{\frac{9}{6}}{\frac{3}{4}}$$

\frac{144}{64} ulushini 16 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$3+\frac{9}{4}-\frac{\frac{9}{6}}{\frac{3}{4}}$$

3 ni \frac{12}{4} kasrga o‘giring.

$$\frac{12}{4}+\frac{9}{4}-\frac{\frac{9}{6}}{\frac{3}{4}}$$

\frac{12}{4} va \frac{9}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{12+9}{4}-\frac{\frac{9}{6}}{\frac{3}{4}}$$

21 olish uchun 12 va 9'ni qo'shing.

$$\frac{21}{4}-\frac{\frac{9}{6}}{\frac{3}{4}}$$

\frac{9}{6} ni \frac{3}{4} ga bo'lish \frac{9}{6} ga k'paytirish \frac{3}{4} ga qaytarish.

$$\frac{21}{4}-\frac{9\times 4}{6\times 3}$$

Surat va maxrajdagi ikkala 2\times 3\times 3 ni qisqartiring.

$$\frac{21}{4}-2$$

2 ni \frac{8}{4} kasrga o‘giring.

$$\frac{21}{4}-\frac{8}{4}$$

\frac{21}{4} va \frac{8}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{21-8}{4}$$

13 olish uchun 21 dan 8 ni ayirish.

$$\frac{13}{4}$$

Omil

$$\frac{13}{2 ^ {2}} = 3\frac{1}{4} = 3,25$$
