(1)0.75×511+611×34,
=0.75×(511+611),
=0.75×1,
=0.75;(2)0.25×4÷0.25×4,
=0.25÷0.25×(4×4),
=1×16,
=16;(3)(110+117)×13+4÷17,
=(110+117)×13+417,
=110×13+117×13+417,
=1310+(1317+417),
=1310+1,
=2310;(4)0.6÷713+87×35-60%,
=0.6×137+87×0.6-0.6,
=0.6×(137+87-1),
=0.6×2,
=1.2;(5)50-7.5-1.3-1.2,
=50-(7.5+1.3+1.2),
=50-10,
=40;(6)(12-13+16)×36,
=12×36-13×36+16×36,
=18-12+6,
=12.
