3/8+9/8*4/3 eching

$$\frac { 3 } { 8 } + \frac { 9 } { 8 } \times \frac { 4 } { 3 }$$

Baholash

$$\frac{15}{8}=1,875$$

Yechim qadamlari

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{9}{8} ni \frac{4}{3} ga ko‘paytiring.

$$\frac{3}{8}+\frac{9\times 4}{8\times 3}$$

\frac{9\times 4}{8\times 3} kasridagi ko‘paytirishlarni bajaring.

$$\frac{3}{8}+\frac{36}{24}$$

\frac{36}{24} ulushini 12 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

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

8 va 2 ning eng kichik umumiy karralisi 8 ga teng. \frac{3}{8} va \frac{3}{2} ni 8 maxraj bilan kasrlarga aylantirib oling.

$$\frac{3}{8}+\frac{12}{8}$$

\frac{3}{8} va \frac{12}{8} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{3+12}{8}$$

15 olish uchun 3 va 12'ni qo'shing.

$$\frac{15}{8}$$

Omil

$$\frac{3 \cdot 5}{2 ^ {3}} = 1\frac{7}{8} = 1,875$$
