（1/3-1/4）÷1/8+5/6 8-5/9-9/1*4 （1/2-1/3+1/6）*24 4/9÷｛4/5-（1/5

Answer 1

（1/3-1/4）÷1/8+5/6

=(1/3-1/4)×8+5/6

=1/3×8-1/4×8+5/6

=8/3-2+5/6

=2/3+5/6

=3/2

8-5/9-9/1*4

=8-5/9-4/9

=8-(5/9+4/9)

=8-1

=7

（1/2-1/3+1/6）*24

=1/2×24-1/3×24+1/6×24

=12-8+4

=8

4/9÷｛4/5-（1/5+1/3）｝

=4/9÷{4/5-1/5-1/3}

=4/9÷{3/5-1/3}

=4/9÷4/15

=4/9×15/4

=5/3
