Yechim qadamlari

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{1}{3} ni \frac{3}{4} ga ko‘paytiring.

$$\frac{1\times 3}{3\times 4}\times 3\left(\frac{1}{10}+\frac{1}{4}\right)\times 4$$

Surat va maxrajdagi ikkala 3 ni qisqartiring.

$$\frac{1}{4}\times 3\left(\frac{1}{10}+\frac{1}{4}\right)\times 4$$

\frac{3}{4} hosil qilish uchun \frac{1}{4} va 3 ni ko'paytirish.

$$\frac{3}{4}\left(\frac{1}{10}+\frac{1}{4}\right)\times 4$$

10 va 4 ning eng kichik umumiy karralisi 20 ga teng. \frac{1}{10} va \frac{1}{4} ni 20 maxraj bilan kasrlarga aylantirib oling.

$$\frac{3}{4}\left(\frac{2}{20}+\frac{5}{20}\right)\times 4$$

\frac{2}{20} va \frac{5}{20} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{3}{4}\times \frac{2+5}{20}\times 4$$

7 olish uchun 2 va 5'ni qo'shing.

$$\frac{3}{4}\times \frac{7}{20}\times 4$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{3}{4} ni \frac{7}{20} ga ko‘paytiring.

$$\frac{3\times 7}{4\times 20}\times 4$$

\frac{3\times 7}{4\times 20} kasridagi ko‘paytirishlarni bajaring.

$$\frac{21}{80}\times 4$$

\frac{21}{80}\times 4 ni yagona kasrga aylantiring.

$$\frac{21\times 4}{80}$$

84 hosil qilish uchun 21 va 4 ni ko'paytirish.

$$\frac{84}{80}$$

\frac{84}{80} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{21}{20}$$

Omil

$$\frac{3 \cdot 7}{2 ^ {2} \cdot 5} = 1\frac{1}{20} = 1,05$$
