375+91/5+(-33/8)+(-42) eching

$$375 + 9 \frac { 1 } { 5 } + ( - 3 \frac { 3 } { 8 } ) + ( - 42 )$$

Baholash

$$\frac{13553}{40}=338,825$$

Yechim qadamlari

45 hosil qilish uchun 9 va 5 ni ko'paytirish.

$$375+\frac{45+1}{5}-\frac{3\times 8+3}{8}-42$$

46 olish uchun 45 va 1'ni qo'shing.

$$375+\frac{46}{5}-\frac{3\times 8+3}{8}-42$$

375 ni \frac{1875}{5} kasrga o‘giring.

$$\frac{1875}{5}+\frac{46}{5}-\frac{3\times 8+3}{8}-42$$

\frac{1875}{5} va \frac{46}{5} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{1875+46}{5}-\frac{3\times 8+3}{8}-42$$

1921 olish uchun 1875 va 46'ni qo'shing.

$$\frac{1921}{5}-\frac{3\times 8+3}{8}-42$$

24 hosil qilish uchun 3 va 8 ni ko'paytirish.

$$\frac{1921}{5}-\frac{24+3}{8}-42$$

27 olish uchun 24 va 3'ni qo'shing.

$$\frac{1921}{5}-\frac{27}{8}-42$$

5 va 8 ning eng kichik umumiy karralisi 40 ga teng. \frac{1921}{5} va \frac{27}{8} ni 40 maxraj bilan kasrlarga aylantirib oling.

$$\frac{15368}{40}-\frac{135}{40}-42$$

\frac{15368}{40} va \frac{135}{40} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{15368-135}{40}-42$$

15233 olish uchun 15368 dan 135 ni ayirish.

$$\frac{15233}{40}-42$$

42 ni \frac{1680}{40} kasrga o‘giring.

$$\frac{15233}{40}-\frac{1680}{40}$$

\frac{15233}{40} va \frac{1680}{40} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{15233-1680}{40}$$

13553 olish uchun 15233 dan 1680 ni ayirish.

$$\frac{13553}{40}$$

Omil

$$\frac{13553}{2 ^ {3} \cdot 5} = 338\frac{33}{40} = 338,825$$
