Amplifici sau simplifici fractia astfel incat sa ai la numitor 100
1/2=50/100=50%
1/4=25/100=25%
3/4=75/100=75%
2/5=40/100=40%
12/25=48/100=48%
9/20=45/100=45%
1/200=0,5/100=0,5%
27/50=54/100=54%
3/400=0,75/100=0,75%
1 3/4=100%+75%=175%
1 1/2=100%+50%=150%
3/8=3·125/1000=375/1000=0,375=37,5/100=37,5%
