Explicație pas cu pas:
d) 15/28:(2 1/10:14/15)/(35/4:12 1/2)=15/28:(21/10·15/14)/(35/4:25/2)=
15/28:(21/10·14/15)/(35/4·2/25)=15/28:(9/4)/(7/10)=15/28:(9/4·10/7)=
15/28:(45/14)=15/28·14/45=14/(28·3)=1/(2·3)=1/6
e) 15/8:(3 3/4:25/16)/(3 3/7:9/14)=15/8:(15/4·16/25)/(24/7·14/9)=
15/8:(12/5)/(48/9)=15/8:(12/5·9/48)=15/8:(9/20)=15/8·(20/9)=25/6
f) 14/15:(1 13/14:9/35)/(1 7/8:21/20)=14/15:(27/14·35/9)/(15/8·20/21)=
14/15:(15/2)/(25/14)=15/8:(15/2·14/25)=14/15:(21/5)=14/15·(5/21)=2/9
