5/2(4/5)-5/6(4/5) eching

$$\frac{ 5 }{ 2 } ( \frac{ 4 }{ 5 } )- \frac{ 5 }{ 6 } ( \frac{ 4 }{ 5 } )$$

Baholash

$$\frac{4}{3}\approx 1,333333333$$

Yechim qadamlari

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{5}{2} ni \frac{4}{5} ga ko‘paytiring.

$$\frac{5\times 4}{2\times 5}-\frac{5}{6}\times \frac{4}{5}$$

Surat va maxrajdagi ikkala 5 ni qisqartiring.

$$\frac{4}{2}-\frac{5}{6}\times \frac{4}{5}$$

2 ni olish uchun 4 ni 2 ga bo‘ling.

$$2-\frac{5}{6}\times \frac{4}{5}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{5}{6} ni \frac{4}{5} ga ko‘paytiring.

$$2-\frac{5\times 4}{6\times 5}$$

Surat va maxrajdagi ikkala 5 ni qisqartiring.

$$2-\frac{4}{6}$$

\frac{4}{6} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$2-\frac{2}{3}$$

2 ni \frac{6}{3} kasrga o‘giring.

$$\frac{6}{3}-\frac{2}{3}$$

\frac{6}{3} va \frac{2}{3} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{6-2}{3}$$

4 olish uchun 6 dan 2 ni ayirish.

$$\frac{4}{3}$$

Omil

$$\frac{2 ^ {2}}{3} = 1\frac{1}{3} = 1,3333333333333333$$
