  1. So sánh >,<,=
    a) 19+7 … 17+9
    Vì 19 + 7 = 26
    Vì 17 + 9 = 26 
    19+7 = 17+9
    b) 17+9 … 17+7
    Vì 17 + 9 = 26
    Vì 17 + 7 = 24
    ⇒ 17+9 > 17+7
     

  2. Giải đáp:
    a)19+7=17+9
    b)17+9>17+7
    Trình bày lời giải:
    a)
    \underbrace{19+7}_{26\quad\quad\quad\quad=}=\quad\quad\underbrace{17+9}_{26}
    b)
    \underbrace{17+9}_{26\quad\quad\quad\quad>}>\quad\quad\underbrace{17+7}_{24}
