\(\dfrac{9}{100}=0,09\left(Đ\right)\)

\(\dfrac{248}{10}=2\dfrac{48}{10}\left(S\right)\)

\(\dfrac{137}{100}=1,37\left(Đ\right)\)

\(\dfrac{8103}{100}=81,03\left(Đ\right)\)

\(\dfrac{2193}{10}=219\dfrac{3}{10}\left(Đ\right)\)

\(\dfrac{18}{100}=1,8\left(S\right)\)

4. 

a. 3,4m = 34dm                               5,09m = 509cm

b. 6,5km = 6500m                           6,15km = 6150m

5.
