解:(1)2.7×64+36×2.7=2.7×(64+36)=2.7×100=270; (2) 48-48÷[150÷(50-25)]=48-48÷[150÷25]=48-48÷6=48-8=40; (3) 6800÷(34×40)=6800÷34÷40=200÷40=5; (4) 12.48-6.35-2.65=12.48-(6.35+2.65)=12.48-9=3.48; (5) (613.6-234.7)+(86.4-65.3)=(613.6+86.4)-(234.7+65.3)=700-300=400; (6) 26000÷125=26×1000÷125=26×(1000÷125)=26×8=208。
