解:(1)3÷-÷3+3,
=4+3,
=7;

(2)4-2×,
=4-
=3;

(3)18÷12×2÷
=18×××21,
=66

(4)1÷12+×,
=1×+×
=(1+)×,
=2×,
=;

(5)2.4×2×,
=2.4××
=0.8;

(6)1÷(3÷1),
=1÷3,
=
分析:(1)先算除法,再加減,
(2)先算乘法,再算減法,
(3)先把除法化成乘法,再進(jìn)行計(jì)算,
(4)先把除法轉(zhuǎn)化成乘法,再根據(jù)乘法分配律進(jìn)行計(jì)算,
(5)根據(jù)乘法的計(jì)算方法進(jìn)行計(jì)算,
(6)先算括號(hào)里面的,再算括號(hào)外面的.
點(diǎn)評(píng):本題主要考查了學(xué)生四則運(yùn)算的計(jì)算能力.
