求11题详细过程！

Answer 1

通过简单的计算。

①，24×{4分之1 + 6％1％至3 1}

= 24×4 + 24×-24 1/6 ×1/3

= 6 + 4-8

= 2

②，1 + 0.45÷0.9-8元7

= 1 + 0.5-7 / 8

= 5/8

③，8分之3×17％+ 5 17分之5×62.5％

= 5/17×（3/8 + 62.5％）的

= 5/17×1

= 5/17

④，9分之4×4点[3- {1}每7-4 16分]

= 4 / 9×[3 / 4-7 / 16 + 1/4]

= 4/9×[3/4 + 1 / 4-7 / 16]

= 4/9×9/16

= 1/4
