Answer 1

a) (3\9+1\4)*(7\7-5\7)=(12\36+9\26)*2\7=21\36*2\7=3\18=1\6

b) 3\5*11\90-4\9:(3\3-1\3)=11\150-4\9:2\3=11\150-2\3=11\150-1\3=11\225

c) (36\90+135\90):(17,5\5+4\5)=171\90:21,5\5=171\90*5\21,5=171\39,5

d) (36\90+135\90):(16\90+36\90)=171\90:54\90=171\90*90\54=171\54

e) (30\6+20\6):16\90=50\6:16\90=50\6*90\16=45\16

sper ca am ajutat macar putin!!
