1. a) 17/4= 4,25 le imparti
7/8= 0,875
99/25= 3,96

2.
25,75= [tex]\frac{2575}{100} = \frac{103}{4}[/tex] (2575 si 100 se simplifica prin 25
2,575= [tex]\frac{2575}{1000} = \frac{103}{40}[/tex] (2575 si 1000 se simplifica prin 25
0,2575= [tex]\frac{2575}{10000} = \frac{103}{400}[/tex] (2575 si 10000 se simplifica prin 25
257,5= [tex]\frac{2575}{10} = \frac{515}{2}[/tex] (2575 si 10 se simplifica prin 5)
0,3= 3/10
0,30= 30/100=3/10
3,84= [tex]\frac{384}{100} =\frac{96}{25}[/tex] ( 384 si 100 se simplifica prin 4)
0, 001= [tex]\frac{1}{1000}[/tex]
0,0002= [tex]\frac{2}{10000} = \frac{1}{5000}[/tex]
