Yechim qadamlari

\frac{28}{16} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

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

2 ni \frac{4}{2} kasrga o‘giring.

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

\frac{4}{2} va \frac{1}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

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

3 olish uchun 4 dan 1 ni ayirish.

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

6 hosil qilish uchun 3 va 2 ni ko'paytirish.

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

7 olish uchun 6 va 1'ni qo'shing.

$$\frac{7}{4}\times \frac{\frac{3}{2}}{\frac{7}{2}}$$

\frac{3}{2} ni \frac{7}{2} ga bo'lish \frac{3}{2} ga k'paytirish \frac{7}{2} ga qaytarish.

$$\frac{7}{4}\times \frac{3}{2}\times \frac{2}{7}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{3}{2} ni \frac{2}{7} ga ko‘paytiring.

$$\frac{7}{4}\times \frac{3\times 2}{2\times 7}$$

Surat va maxrajdagi ikkala 2 ni qisqartiring.

$$\frac{7}{4}\times \frac{3}{7}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{7}{4} ni \frac{3}{7} ga ko‘paytiring.

$$\frac{7\times 3}{4\times 7}$$

Surat va maxrajdagi ikkala 7 ni qisqartiring.

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