Yechim qadamlari

7 va 8 ning eng kichik umumiy karralisi 56 ga teng. \frac{2}{7} va \frac{5}{8} ni 56 maxraj bilan kasrlarga aylantirib oling.

$$\frac{16}{56}+\frac{35}{56}+4\times 375$$

\frac{16}{56} va \frac{35}{56} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{16+35}{56}+4\times 375$$

51 olish uchun 16 va 35'ni qo'shing.

$$\frac{51}{56}+4\times 375$$

1500 hosil qilish uchun 4 va 375 ni ko'paytirish.

$$\frac{51}{56}+1500$$

1500 ni \frac{84000}{56} kasrga o‘giring.

$$\frac{51}{56}+\frac{84000}{56}$$

\frac{51}{56} va \frac{84000}{56} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{51+84000}{56}$$

84051 olish uchun 51 va 84000'ni qo'shing.

$$\frac{84051}{56}$$
