Explicație pas cu pas:
a= (1/3+1/5): 1/2 =(5+3)/15×2=8×2/15=16/15
b = 1/2×(1/3-1/5)=(5-3)/15×1/2=2/15×1/2=1/15
a/b=16/15:1/15=16 a este de 16 ori mai mare decat b
Răspuns:
a= (⁵⁾1/3+³⁾1/5): 1/2
a=(5/15+3/15):1/2
a=8/15·2/1
a=16/15
b = 1/2*(⁵⁾1/3-³⁾1/5)
b=1/2·(5/15-3/15)
b=1/2·2/15
b=2/30=>b=1/15
a=16b=>a=16·1/15=>a=16/15(adevarat)
a > b de 16 ori
