Câu trả lời (1)

  • a) Số phần tương ứng với 105 cây là:

    1-(1/4+2/5)= 7/20 ( phần số cây )

    Tổng số cây cả ba lớp trồng là:

    105 : 7/20 = 300 ( cây )

    b) Số cây lớp 6A trồng được là:

    300.1/4= 75 ( cây )

    Tỉ số phần trăm số cây lớp 6A trồng được so với tổng số cây là:

    75/300.100%= 25% ( so với tổng số cây )
