$$5 \frac { 2 } { 9 } - 2 \frac { 4 } { 15 }$$

Baholash

$$\frac{133}{45}\approx 2,955555556$$

Yechim qadamlari

45 hosil qilish uchun 5 va 9 ni ko'paytirish.

$$\frac{45+2}{9}-\frac{2\times 15+4}{15}$$

47 olish uchun 45 va 2'ni qo'shing.

$$\frac{47}{9}-\frac{2\times 15+4}{15}$$

30 hosil qilish uchun 2 va 15 ni ko'paytirish.

$$\frac{47}{9}-\frac{30+4}{15}$$

34 olish uchun 30 va 4'ni qo'shing.

$$\frac{47}{9}-\frac{34}{15}$$

9 va 15 ning eng kichik umumiy karralisi 45 ga teng. \frac{47}{9} va \frac{34}{15} ni 45 maxraj bilan kasrlarga aylantirib oling.

$$\frac{235}{45}-\frac{102}{45}$$

\frac{235}{45} va \frac{102}{45} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{235-102}{45}$$

133 olish uchun 235 dan 102 ni ayirish.

$$\frac{133}{45}$$

Omil

$$\frac{7 \cdot 19}{3 ^ {2} \cdot 5} = 2\frac{43}{45} = 2,9555555555555557$$
