  • 1. 0,8 + 1/4
    = 8/10 + 1/4
    = 16/20 + 5/20
    = 21/20

    2. 0,45 + 25
    = 25,45

    3. 1 3/4 + 2,6
    = 7/4 + 26/10
    = 35/20 + 52/20
    = 87/20

    4. 3,25 + 2 1/2 + 20%
    = 325/100 + 5/2 + 20/100
    = 325/100 + 250/100 + 20/100
    =595/100

    5. 60% + 4,15 + 2 2/5
    = 60/100 + 415/100 + 12/5
