$$\frac { 5 } { 12 } - ( - \frac { 1 } { 3 } ) + ( - \frac { 1 } { 4 } )$$

Baholash

$$\frac{1}{2}=0,5$$

Yechim qadamlari

-\frac{1}{3} ning teskarisi \frac{1}{3} ga teng.

$$\frac{5}{12}+\frac{1}{3}-\frac{1}{4}$$

12 va 3 ning eng kichik umumiy karralisi 12 ga teng. \frac{5}{12} va \frac{1}{3} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$\frac{5}{12}+\frac{4}{12}-\frac{1}{4}$$

\frac{5}{12} va \frac{4}{12} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{5+4}{12}-\frac{1}{4}$$

9 olish uchun 5 va 4'ni qo'shing.

$$\frac{9}{12}-\frac{1}{4}$$

\frac{9}{12} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{3}{4}-\frac{1}{4}$$

\frac{3}{4} va \frac{1}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{3-1}{4}$$

2 olish uchun 3 dan 1 ni ayirish.

$$\frac{2}{4}$$

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

$$\frac{1}{2}$$

Omil

$$\frac{1}{2} = 0,5$$
