\frac{2\times 4+1}{4} ni \frac{7}{4} ga bo'lish \frac{2\times 4+1}{4} ga k'paytirish \frac{7}{4} ga qaytarish.

$$\frac{\left(2\times 4+1\right)\times 4}{4\times 7}=\frac{\frac{3}{2}}{5}$$

Surat va maxrajdagi ikkala 4 ni qisqartiring.

$$\frac{1+2\times 4}{7}=\frac{\frac{3}{2}}{5}$$

8 hosil qilish uchun 2 va 4 ni ko'paytirish.

$$\frac{1+8}{7}=\frac{\frac{3}{2}}{5}$$

9 olish uchun 1 va 8'ni qo'shing.

$$\frac{9}{7}=\frac{\frac{3}{2}}{5}$$

\frac{\frac{3}{2}}{5} ni yagona kasrga aylantiring.

$$\frac{9}{7}=\frac{3}{2\times 5}$$

10 hosil qilish uchun 2 va 5 ni ko'paytirish.

$$\frac{9}{7}=\frac{3}{10}$$

7 va 10 ning eng kichik umumiy karralisi 70 ga teng. \frac{9}{7} va \frac{3}{10} ni 70 maxraj bilan kasrlarga aylantirib oling.

$$\frac{90}{70}=\frac{21}{70}$$

\frac{90}{70} va \frac{21}{70} ni taqqoslang.
