7/2*(13/6+9/9)= eching

$$\frac { 7 } { 2 } \cdot ( \frac { 13 } { 6 } + \frac { 9 } { 9 } ) =$$

Baholash

$$\frac{133}{12}\approx 11,083333333$$

Yechim qadamlari

1 ni olish uchun 9 ni 9 ga bo‘ling.

$$\frac{7}{2}\left(\frac{13}{6}+1\right)$$

1 ni \frac{6}{6} kasrga o‘giring.

$$\frac{7}{2}\left(\frac{13}{6}+\frac{6}{6}\right)$$

\frac{13}{6} va \frac{6}{6} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{7}{2}\times \frac{13+6}{6}$$

19 olish uchun 13 va 6'ni qo'shing.

$$\frac{7}{2}\times \frac{19}{6}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{7}{2} ni \frac{19}{6} ga ko‘paytiring.

$$\frac{7\times 19}{2\times 6}$$

\frac{7\times 19}{2\times 6} kasridagi ko‘paytirishlarni bajaring.

$$\frac{133}{12}$$

Omil

$$\frac{7 \cdot 19}{2 ^ {2} \cdot 3} = 11\frac{1}{12} = 11,083333333333334$$
