Answer 1

7分之5÷4分之3÷6分之5
=(5/7)/(3/4)/(5/6)
=(5*4/7*3)/(5/6)
=(20/21)/(5/6)
=20*6/21*5
=4*2/7
=8/7

4分之1÷8分之3×7分之6
=(1/4)/(3/8)(6/7)
=(1/4)(8/3)(6/7)
=(2/3)(6/7)
=4/7

12分之5×5分之2÷8分之9
=(5/12)(2/5)/(9/8)
=(1/6)/(9/8)
=(1/6)(8/9)
=4/27

125÷9分之1÷8分之1
=125/(1/9)/(1/8)
=125(9)/(1/8)
=(125*9)(8)
=9000

5分之3÷6×15分之4
=(3/5)/6*(4/15)
=(1/10)*(4/15)
=4/75

4分之3÷5分之6÷16分之15
=(3/4)/(6/5)/(15/16)
=(15/24)/(15/16)
=16/24
=2/3

3分之7×7分之5÷3分之4
=(7/3)(5/7)/(4/3)
=(5/3)/(4/3)
=5/4

16分之11÷8分之15×33分之2
=(11/16)/(15/8)(2/33)
=(11/16)(8/15)(2/33)
=(88/16*15)(2/33)
=88/8*15*33
=11/15*33
=1/45
