2 Jawaban

  • 1 2/4 + 2 2/5 × 3/4
    = 1½ + 2 2/5 × 3/4
    = 3/2 + 12/5 × 3/4
    = 3/2 + 9/5
    = 15/10 + 18/10
    = 33/10
    = 3 3/10
  • Jawab :

    1 2/4 + 2 2/5 × 3/4

    Langkah 1

    2 2/5 × 3/4
    = 12/5 × 3/4
    = 12 × 3/ 5 × 4
    = 36/20
    = 9 × 4/ 5 × 4
    = 1 4/5

    Langkah 2

    1 2/4 + 1 4/5
    = 1 1 × 2/ 2 × 2 + 1 4/5
    = 3/2 + 9/5
    = 5 × 3 + 2 × 9/ 10
    = 33/10
    = 3 3/10

    Jadi hasil dari 1 2/4 + 2 2/5 × 3/4 = 3 3/10
