Yechim qadamlari

\frac{3}{8} ni \frac{2}{3} ga bo'lish \frac{3}{8} ga k'paytirish \frac{2}{3} ga qaytarish.

$$\frac{3}{4}+\frac{3}{8}\times \frac{3}{2}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{3}{8} ni \frac{3}{2} ga ko‘paytiring.

$$\frac{3}{4}+\frac{3\times 3}{8\times 2}$$

\frac{3\times 3}{8\times 2} kasridagi ko‘paytirishlarni bajaring.

$$\frac{3}{4}+\frac{9}{16}$$

4 va 16 ning eng kichik umumiy karralisi 16 ga teng. \frac{3}{4} va \frac{9}{16} ni 16 maxraj bilan kasrlarga aylantirib oling.

$$\frac{12}{16}+\frac{9}{16}$$

\frac{12}{16} va \frac{9}{16} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{12+9}{16}$$

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

$$\frac{21}{16}$$

Omil

$$\frac{3 \cdot 7}{2 ^ {4}} = 1\frac{5}{16} = 1,3125$$
