Răspuns:
a) 3/5 : 2 intregi si 1/10 = 3/5 : 2*10+1/10 - e totul supra 10 incepand cu 2*10
=3/5 :20+1/10 =3/5:21/10 =3/5 *10/21 =30/105 =2/7
b) 8/13:40/26 = 8/13*26/40 =1*2/5 =2/5
c) 1 :16/5 =1 *5/16 =5/16
d) 3:6/11 =3*11/6 =33/6 =11/2
e) 1/7 :5/14 = 1/7*14/5 =14/35 =2/5
f) 3intregi si 1/7 :22/21 = 3*7+1/7 *21/22 = 21+1/7 *21/22 =22/7 *21/22 =1*3/1=3
