  • 35 =20+15 70/10 =7
    128/10 =12,8
    7 + 8/10 =70/10+8/10=78/10 =7,8
    12 = 120/10
    28 + 0= 280/10
     3/10 +  8/10 = 11/10

  • 35 = 30 + 5

    70 / 10 = 7

    128 / 10 = 12,8

    7 + 8 / 10 = 70 / 10 + 8 / 10 = 78 / 10 = 7,8

    12 = 120 / 10

    28 + 0 = 280 / 10

    5 / 10 + 6 / 10 = 11 / 10
