(12分之7-8分之3)×24-9分之5
=7/12x24-3/8x24-5/9
=14-9-5/9
=5-5/9
=4又9分之4
32分之9÷[4分之3-(16分之7-4分之1)]
=9/21÷(3/4-7/16+1/4)
=9/21÷(3/4+1/4-7/16)
=9/21÷(1-7/16)
=9/21÷9/16
==9/21x16/9
=16/21
14分之9÷(6分之5-4分之3)×24分之7
=9/14÷(10/12-9/12)×7/24
=9/14÷1/12×7/24
=9/14×(12×7/24)
=9/14×7/2
=9/4
16分之5×7分之4+1÷5分之16+7分之3×16分之5
=5/16x4/7+1x5/16+3/7x5/16
=5/16x(4/7+1+3/7)
=5/16x(4/7+3/7+1)
=5/16x2
