Trả lời

3,2=32/10

Chúc hok tốt !

32/10 hoc tot nha

3,2=16/5

1/2

5/ 10= 1/ 2

\(\dfrac{1}{2}\)

5 dm = 5/10 m=1/2 m

12 cm = 12/100 m=3/25m

45 cm = 45/100 m=9/20 m

30 dm^2 = 30/100 m^2 = 3/10 m^2

\(5\)\(dm\) =   \(\frac{5}{10}\) \(m\)

\(12\) \(cm\) =   \(\frac{12}{100}\) \(m\)

\(45\) \(cm\) =  \(\frac{45}{100}\) \(m\)

\(30\) \(dm^2\) =  \(\frac{30}{100}\) \(m^2\)

bằng 2, 5 nhé

25/100=1/4

0,5 5/10=1/2 

25 % = 1/4

0.5 = 1/2

25/100=1/4

0,5 5/10=1/2 

@_@

\(3,5=\dfrac{7}{2}\)

3,5 = 35/10 = 7/2

\(=\dfrac{35}{10}=\dfrac{7}{2}\)

10/666

\(10,666=\dfrac{10666}{1000}=\dfrac{5333}{500}\)

\(0,3\left(5\right)=\dfrac{3}{2}\)

\(0,3\left(5\right)=3,2.\dfrac{1}{9}=\dfrac{32}{10}.\dfrac{1}{9}=\dfrac{16}{45}\)

0,3(5)= \(\dfrac{3}{2}\)

nhớ tích cho mình với nhé 

1/2

\(\dfrac{1}{2}\)

vẫn vậy
