0,15-3/20=
1/2+0,36=
1/8+0,525=

Answer 1

0,3+1/3=3/10+1/3=(9+10)/30=19/30
0,2+2/3=2/10+2/3=(6+12)/30=18/30=3/5
0,6-5/9=6/10-5/9=(54-50)/90=6/90=1/15
2/7+0,25=2/7+25/100=2/7+1/4=(8+7)/28=15/28
1/5+0,52=1/5+52/100=(20+52)/100=72/100=18/25
0,15-3/20=15/100-3/20=3/20-3/20=0
1/2+0,36=1/2+36/100=1/2+9/25=(25+18)/50=43/50
1/8+0,525=1/8+525/1000=1/8+21/40=(5+21)/40=26/40=13/20
