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
中国
X-25%X = 8分之3
(1-25%)×= 3/8
3 / 4X = 3/8
X = 3/8 ÷3/4
X = 1/2
