(2又7/9除以1/6+1/3)×(32/5-1又2/5×12/17)
问题描述：
(2又7/9除以1/6+1/3)×(32/5-1又2/5×12/17)
答
=(25/6*6+1/3)*(32/5-7/5*12/17）
=(50/3+1/3)*(32/5-84/85)
=17* (544/85-84/85)
=17* 92/17
=289/17 * 92/17
=197/17
答
(2又7/9除以1/6+1/3)×(32/5-1又2/5×12/17)
=(50/3+1/3)×(32/5-7/5×12/17)
=(50/3+1/3)X(32/5-84/85)
=(51/3)X(92/17)
=92
答
(2又7/9除以1/6+1/3)×(32/5-1又2/5×12/17)
=(25/9X6+1/3)X(32/5-7/5X12/17)
=(50/3+1/3)X(32/5-84/85)
=(51/3)X(92/17)
=92
答
(2又7/9除以1/6+1/3)×(32/5-1又2/5×12/17)
=92
