Cho cac so thap phan  :12,05;12,050;12,005;12,0500;12,0005.Nhung so thap phan bang nhau la:

A)12,05=12,050=12,005                                         C)12,05=12,050=12,0500

B)12,005=12,0005                                                 D)12,05=12,005=12,0500=12,0005

a: \(0.45=\dfrac{9}{20}\)

b: \(1.325=\dfrac{1325}{1000}\)

c: \(0.038=\dfrac{38}{1000}\)

làm ơn giúp

a) 0,45 = 9/20
b) 1,325 = 53/40
c) 0,038 = 19/500
d) 12,005 = 2401/200
Chúc bạn học tốt nhé
