Answer 1

d)

45/6+13/17+5/30+4/17=

=85×45+30×13+17×5+30×4 tot ăsta supra/510=

=3825+390+85+120 tot asta supra/510=

=4215+205 totul supra/510=

=4420/510 (simplificat cu 10)=

=442/51







e)

2/9+19/25+50/18+38/50=

=50×2+18×19+25×50+9×38 tot asta supra/450=

=100+342+1250+342 tot asta supra/450=

=442+1592 totul supra/450=

=2034/450 (simplificat cu 3)=

=678/150 (simplificat cu 3)=

=226/50 (simplificat cu 2)=
