Yechim qadamlari

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

$$\frac{1}{2}-3-3+100$$

3 ni \frac{6}{2} kasrga o‘giring.

$$\frac{1}{2}-\frac{6}{2}-3+100$$

\frac{1}{2} va \frac{6}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{1-6}{2}-3+100$$

-5 olish uchun 1 dan 6 ni ayirish.

$$-\frac{5}{2}-3+100$$

3 ni \frac{6}{2} kasrga o‘giring.

$$-\frac{5}{2}-\frac{6}{2}+100$$

-\frac{5}{2} va \frac{6}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-5-6}{2}+100$$

-11 olish uchun -5 dan 6 ni ayirish.

$$-\frac{11}{2}+100$$

100 ni \frac{200}{2} kasrga o‘giring.

$$-\frac{11}{2}+\frac{200}{2}$$

-\frac{11}{2} va \frac{200}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-11+200}{2}$$

189 olish uchun -11 va 200'ni qo'shing.
