Question

计算下面各题（能简便的要用简便方法） 
（0.25+(3)/(4)）÷（1-0.99）
(1)/(6)÷(4)/(3)+(1)/(4)×(1)/(6)
（(1)/(3)+(2)/(3)×(3)/(4)）×（75%+2(1)/(4)）              
8(1)/(8)+(3)/(4)+(7)/(8)+(1)/(4)．

Answer 1

（1）（0.25+(3)/(4)）÷（1-0.99）
=1÷0.01
=100；

（2）(1)/(6)÷(4)/(3)+(1)/(4)×(1)/(6)
=(1)/(6)×(3)/(4)+(1)/(4)×(1)/(6)
=（(3)/(4)+(1)/(4)）×(1)/(6)
=1×(1)/(6)
=(1)/(6)；

（3）（(1)/(3)+(2)/(3)×(3)/(4)）×（75%+2(1)/(4)）
=（(1)/(3)+(1)/(2)）×（0.75+2.25）
=(5)/(6)×3
=(5)/(2)；
              
（4）8(1)/(8)+(3)/(4)+(7)/(8)+(1)/(4)
=8(1)/(8)+(7)/(8)+（(3)/(4)+(1)/(4)）
=9+1
=10．
