Yechim qadamlari

7 hosil qilish uchun 1 va 7 ni ko'paytirish.

$$\frac{5}{24}\times \frac{7+5}{7}+\frac{2}{4}\times \frac{5}{7}$$

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

$$\frac{5}{24}\times \frac{12}{7}+\frac{2}{4}\times \frac{5}{7}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{5}{24} ni \frac{12}{7} ga ko‘paytiring.

$$\frac{5\times 12}{24\times 7}+\frac{2}{4}\times \frac{5}{7}$$

\frac{5\times 12}{24\times 7} kasridagi ko‘paytirishlarni bajaring.

$$\frac{60}{168}+\frac{2}{4}\times \frac{5}{7}$$

\frac{60}{168} ulushini 12 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{5}{14}+\frac{2}{4}\times \frac{5}{7}$$

\frac{2}{4} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{5}{14}+\frac{1}{2}\times \frac{5}{7}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{1}{2} ni \frac{5}{7} ga ko‘paytiring.

$$\frac{5}{14}+\frac{1\times 5}{2\times 7}$$

\frac{1\times 5}{2\times 7} kasridagi ko‘paytirishlarni bajaring.

$$\frac{5}{14}+\frac{5}{14}$$

\frac{5}{14} va \frac{5}{14} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{5+5}{14}$$

10 olish uchun 5 va 5'ni qo'shing.

$$\frac{10}{14}$$

\frac{10}{14} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
