Answer 1

    19/4 = (16+3)/4 = 4 si 3/4; 4 < 19/4 < 5
    27/5 = (25+2)/5 = 5 si 2/5; 5 < 27/5 < 6
    9/5 = (5+4)/5 = 1 si 4/5; 1 < 9/5 < 2
    29/2 = (28+1)/2 = 14 si 1/2; 14 < 29/2 < 15
    13/6 = (12+1)/6 = 2 si 1/6; 2 < 13/6 < 3
    19/7 = (14+5)/7 = 2 si 5/7; 2 < 19/7 < 3
    27% =27/100 ; 0 < 26% < 1
    135% = 135/100 = (100+35)/100 = 1 si 35/100; 1 < 135% < 2
    225% = 225/100 = (200+25)/100 = 2 si 25/100; 2 < 225% < 3
