    Đáp án:

     dưới nha !

    Giải thích các bước giải:

    `2/3 + 4/3=(2+4)/3=6/3=2`

    `5/6-1/2=5/6-3/6=2/6=1/3`

    `2/3xx3/4=(2xx3)/(3xx4)=6/12=1/2`

    `5/6÷1/2=5/6xx2=10/6=5/3`

    `3/6+1/4×3/4=3/6+3/16=24/48+9/48=11/16`

    `2/3 + 4/3=6/3=2`

    `5/6- 1/2=5/6-3/6=2/6=1/3`

    `2/3× 3/4=6/12=1/2`

    `5/6 : 1/2=5/6×2=10/6=5/3`

    `3/6+1/4×3/4=3/6+3/16=1/2+3/16=8/16+3/16=11/16`
