Answer 1

Răspuns:

Explicație pas cu pas:

a) (43×35-1319)/35-(25-4)/14=186/35-21/14=186/35-3/2=

(186×2-105)/70=(372-105)/70=267/70

b)2585/26-(926/13-605/26)=2585/26-(1852-605)/26=2585/26-1247/26=

=1338/26=669/13

c)767/30-[173/18-(246/5-1033/24-137/120)]=

767/30-[173/18-(246×24-1033×5-137)/120]=767/30-(173/18-602/120)

=767/30-(173/18-301/60)=767/30-(173×10-301×3)/180=767/30-827/180=

=(767×6-826)/180=(4602-826)/180=3775/180=755/36
