Answer 1

1) ( 60+60:6+(60:6*3))-(10+10:2)=
    =(60+10+(10*3))-(10+5)
    =(60+10+30)-15
    =(70+30)-15
    =100-15
    =85 baloane raman in cutie

2) br=60 baloane rosii
    bg=60:6=10 baloane.galbene
    ba=10*3=30 baloane albastre
60+10+30=100 baloane in total
100-10-10:2=
=100-10-5
=90-5
=85 baloane raman in cutie
