10:(12,4-12,3)-28,376=
(3,5:0,5+1,2)•2-1

Answer 1

30+(26,2-0,16):1,23=
=30+26,04:1,23=
=30+21, (17073)=
=30/1+ 2117073-21 totul supra/99999=
=30/1+ 2117052/99999=
=99999×30+2117052 tot ăsta supra/99999=
=2999970+2117052 totul supra/99999=
=5117022/99999=
=51, (17073)

(este 51, perioada 17073)







10:(12,4-12,3)-28,376=
=10:0,1-28,376=
=100-28,376=
=71,624






(3,5:0,5+1,2)•2-1=
=(7+1,2)×2-1=
=8,2×2-1=
=16,4-1=
=15,4
