2. Jasurning sumkasi massasi 3 3/5 kg. Shohibaning sumkasi massasi esa 2 3/4 kg. Ikkala sumkaning umumiy massasini necha kilogramm? Javobingizni aralash son ko‘rinishida ifodalang.

Aralash sonlarni noto‘g‘ri kasrga aylantiramiz:

\(3\frac{3}{5}=\frac{18}{5}\),   \(2\frac{3}{4}=\frac{11}{4}\).

Umumiy massani topamiz:

\[\frac{18}{5}+\frac{11}{4}=\frac{72}{20}+\frac{55}{20}=\frac{127}{20}=6\frac{7}{20}\text{ kg}.\]

Javob: \(6\frac{7}{20}\) kg.
