6],
=[66/65]×[5/6],
=[11/13];
(2)[7/15]-[2/15]÷0.3,
=[7/15]-[4/9],
=[1/45];
(3)﹙[11/15]-[4/5]﹢[7/20]﹚÷[1/60],
=[11/15×60−
4
5]×60+

20×60,
=44-48+21,
=65-48,
=17;
(4)37×[35/36],
=(36+1)×[35/36],
=36×[35/36]+1×[35/36],
=35+[35/36],
=35[35/36];
(5)﹙4-[5/12]÷[1/6]﹚÷0.1,
=(4-2.5)÷0.1,
=1.5÷0.1,
=15;
(6)0.75×46+[3/4]×55-3÷4,
=[3/4]×(46+55-1),
=[3/4]×100,
=75.
点评:
