31/3-5/6 eching

$$3 \frac { 1 } { 3 } - \frac { 5 } { 6 }$$

Baholash

$$\frac{5}{2}=2,5$$

Yechim qadamlari

9 hosil qilish uchun 3 va 3 ni ko'paytirish.

$$\frac{9+1}{3}-\frac{5}{6}$$

10 olish uchun 9 va 1'ni qo'shing.

$$\frac{10}{3}-\frac{5}{6}$$

3 va 6 ning eng kichik umumiy karralisi 6 ga teng. \frac{10}{3} va \frac{5}{6} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$\frac{20}{6}-\frac{5}{6}$$

\frac{20}{6} va \frac{5}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{20-5}{6}$$

15 olish uchun 20 dan 5 ni ayirish.

$$\frac{15}{6}$$

\frac{15}{6} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{5}{2}$$

Omil

$$\frac{5}{2} = 2\frac{1}{2} = 2,5$$
