Question

Viết (theo mẫu).

Mẫu: \(\dfrac{31}{10}=\dfrac{30+1}{10}=\dfrac{30}{10}+\dfrac{1}{10}=3+\dfrac{1}{10}=3\dfrac{1}{10}\)

\(\dfrac{57}{10}\)                     \(\dfrac{703}{100}\)                    \(\dfrac{63}{10}\)                      \(\dfrac{3005}{1000}\)

Answer 1

`57/10 = (50 + 7)/10 = 50/10 + 7/10 = 5 + 7/10 = 5 7/10`

`703/100 = (700 + 3)/100 = 700/100 + 3/100 = 7 + 3/100 = 7 3/100`

`63/10 = (60 + 3)/10= 60/10 + 3/10 = 6 + 3/10 =  6 3/10`

`3005/1000 = (3000 + 5)/1000 = 3000/1000 + 5/1000 = 3 + 5/1000 = 3 5/1000 = 3 1/200
