Question

算一算：
5.25-2.125+（4.75-3.375）
0.125×5.25+3.75÷8+(1)/(8)
45×19+4680÷12
(9)/(25)÷6+1÷6×(6)/(25)．

Answer 1

（1）5.25-2.125+（4.75-3.375）
=（5.25+4.75）-（2.125+3.375）
=10-5.5
=4.5

（2）0.125×5.25+3.75÷8+(1)/(8)
=(1)/(8)×5.25+3.75×(1)/(8)+(1)/(8)
=(1)/(8)×（5.25+3.75+1）
=(1)/(8)×10
=(5)/(4)

（3）45×19+4680÷12
=855+390
=1245

（4）(9)/(25)÷6+1÷6×(6)/(25)
=(9)/(25)×(1)/(6)+(1)/(6)×(6)/(25)
=（(9)/(25)+(6)/(25)）×(1)/(6)
=(3)/(5)×(1)/(6)
=(1)/(10)
