1/3/frac{2{3}}+2/15+3/5 eching

$$\frac { \frac { 1 } { 3 } } { \frac { 2 } { 3 } } + \frac { 2 } { 15 } + \frac { 3 } { 5 }$$

Baholash

$$\frac{37}{30}\approx 1,233333333$$

Yechim qadamlari

\frac{1}{3} ni \frac{2}{3} ga bo'lish \frac{1}{3} ga k'paytirish \frac{2}{3} ga qaytarish.

$$\frac{1}{3}\times \frac{3}{2}+\frac{2}{15}+\frac{3}{5}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{1}{3} ni \frac{3}{2} ga ko‘paytiring.

$$\frac{1\times 3}{3\times 2}+\frac{2}{15}+\frac{3}{5}$$

Surat va maxrajdagi ikkala 3 ni qisqartiring.

$$\frac{1}{2}+\frac{2}{15}+\frac{3}{5}$$

2 va 15 ning eng kichik umumiy karralisi 30 ga teng. \frac{1}{2} va \frac{2}{15} ni 30 maxraj bilan kasrlarga aylantirib oling.

$$\frac{15}{30}+\frac{4}{30}+\frac{3}{5}$$

\frac{15}{30} va \frac{4}{30} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{15+4}{30}+\frac{3}{5}$$

19 olish uchun 15 va 4'ni qo'shing.

$$\frac{19}{30}+\frac{3}{5}$$

30 va 5 ning eng kichik umumiy karralisi 30 ga teng. \frac{19}{30} va \frac{3}{5} ni 30 maxraj bilan kasrlarga aylantirib oling.

$$\frac{19}{30}+\frac{18}{30}$$

\frac{19}{30} va \frac{18}{30} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{19+18}{30}$$

37 olish uchun 19 va 18'ni qo'shing.

$$\frac{37}{30}$$

Omil

$$\frac{37}{2 \cdot 3 \cdot 5} = 1\frac{7}{30} = 1,2333333333333334$$
