能简便简便 （1/3-1/4)除1/2+5/6 （1/2+1/3-1/4)X24 4/9X1/6+5/9除6 4/7-3

Answer 1

（1/3-1/4)除1/2+5/6

=1/3除1/2-1/4除1/2+5/6

=2/3-1/2+5/6

=4/6-3/6+5/6

=6/6

=1

（1/2+1/3-1/4)X24

=1/2 x24 +1/3 x24- 1/4x24

=12+8-6

=14

4/9X1/6+5/9除6

=4/9X1/6+5/9X1/6

=(4/9+5/9)X1/6

=9/9X1/6

=1/6

4/7-3/7除15/14

=4/7-3/7 x14/15

=4/7-2/5

=20/35-14/35

=6/35
