Question

 viết các phân số sau thành số thập phân:\(\dfrac{1}{8}\),\(\dfrac{49}{140}\),\(\dfrac{2}{125}\)

Answer 1

\(\dfrac{1}{8}=0,125\\ \dfrac{49}{140}=\dfrac{7}{20}=0,35\\ \dfrac{2}{125}=0,016\)

Answer 2

`1/8= 0,125`

`49/140=0,35`

`2/125=0,016`

Answer 3

\(\dfrac{1}{8}=\dfrac{1.125}{8.125}=\dfrac{125}{1000}=0,125\)

\(\dfrac{49}{140}=\dfrac{49:7}{140:7}=\dfrac{7}{20}=\dfrac{7.5}{20.5}=\dfrac{35}{100}=0,35\)

\(\dfrac{2}{125}=\dfrac{2.8}{125.8}=\dfrac{16}{1000}=0,016\)

Answer 4

\(\dfrac{1}{8}=0,125\)

\(\dfrac{49}{140}=0,35\)

\(\dfrac{2}{125}=0,016\)

Answer 5

1/8=0,125   ,  49/140=0,35  , 2/125=0,016
