\(\dfrac{54}{10}=5,4\)
\(4\dfrac{78}{1000}=4+\dfrac{78}{1000}=4+0,078=4,078\)
\(18\dfrac{4}{100}=18+\dfrac{4}{100}=18+0,04=18,04\)

\(12\dfrac{5}{100}=\dfrac{241}{20}=12,05\)
\(17\dfrac{23}{100}=\dfrac{1723}{100}=17,23\)
\(10\dfrac{7}{10}=\dfrac{107}{10}=10,7\)

a) \(10\frac{7}{10}=\frac{107}{10}=10,7\)
b) \(5\frac{15}{100}=\frac{515}{100}=5,15\)
c) \(34\frac{3}{100}=\frac{3403}{100}=34,03\)
d) \(68\frac{136}{1000}=\frac{68136}{1000}=68,136\)
e) \(5\frac{5}{1000}=\frac{5005}{1000}=5,005\)
g) \(100\frac{1}{100}=\frac{10001}{100}=100,01\)
2 và 17/1000=1000x2+17/1000
2017/1000
vậy 2 và 17/1000=2017/1000
\(2\frac{17}{1000}=2+\frac{17}{1000}=\frac{2000}{1000}+\frac{17}{1000}=\frac{2017}{1000}\)
