  （1/2-1/3）×3/4÷1/4

=1/2×3/4÷1/4-1/3×3/4÷1/4

=1/2×（3/4÷1/4）-1/3×（3/4÷1/4）

=1/2×4-1/3×4

=2-4/3

=2/3

解一

(1/2-1/3)×3/4÷1/4

=1/6×3/4×4/1

=1/8×4

=1/2

解二

(1/2-1/3)×3/4÷1/4

=(1/2-1/3)×(3/4÷1/4)

=(1/2-1/3)×3

=1/2×3-1/3×6

=3/2-1

=1/2

（1/2-1/3）×3/4÷1/4

=（3/6-2/6）×(3/4÷1/4)

=1/6x(3/4x4)

=1/6x3

=1/2
