Yechim qadamlari

\frac{6\times 8+3}{8} ni \frac{4\times 25+2}{25} ga bo'lish \frac{6\times 8+3}{8} ga k'paytirish \frac{4\times 25+2}{25} ga qaytarish.

$$\frac{\left(6\times 8+3\right)\times 25}{8\left(4\times 25+2\right)}$$

48 hosil qilish uchun 6 va 8 ni ko'paytirish.

$$\frac{\left(48+3\right)\times 25}{8\left(4\times 25+2\right)}$$

51 olish uchun 48 va 3'ni qo'shing.

$$\frac{51\times 25}{8\left(4\times 25+2\right)}$$

1275 hosil qilish uchun 51 va 25 ni ko'paytirish.

$$\frac{1275}{8\left(4\times 25+2\right)}$$

100 hosil qilish uchun 4 va 25 ni ko'paytirish.

$$\frac{1275}{8\left(100+2\right)}$$

102 olish uchun 100 va 2'ni qo'shing.

$$\frac{1275}{8\times 102}$$

816 hosil qilish uchun 8 va 102 ni ko'paytirish.

$$\frac{1275}{816}$$

\frac{1275}{816} ulushini 51 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
