1 Jawaban

  • A. 20 = 2 x 2 x 5
    80 = 2 x 2 x 2 x 2 x 5
    fpb = 2 x 2 x 5 = 20
    kpk = 2 x 2 x 2 x 2 x 5 = 80
    B. 12 = 2 x 2 x 3
    20 = 2 x 2 x 5
    80 = 2 x 2 x 2 x 2 x 2 x 5
    fpb = 2 x 2 = 4
    kpk = 2 x 2 x 2 x 2 x 2 x 3 x 5 = 480
    C. 30 = 2 x 3 x 5
    90 = 2 x 3 x 3 x 5
    fpb = 2 x 3 x 5 = 30
    kpk = 2 x 3 x 3 x 5 = 90
    semoga terbantu
