Question

0,(5)-0,0(8)

Answer 1

\(=\dfrac{5}{9}-\dfrac{4}{45}=\dfrac{7}{15}\)

Answer 2

 

 

Answer 3

0,(5) - 0,0(8)

= \(\dfrac{5}{9}-\dfrac{4}{45}\)

= \(\dfrac{25}{45}-\dfrac{4}{45}\)

= \(\dfrac{21}{45}=\dfrac{7}{15}=0,4\left(6\right)\)

Answer 4

 

`0,(5) - 0,0(8)= 0,(1).5-  0,0(1) .8 = 1/9.5 -  1/90 . 8 = 5/9 - 4/45=7/15`

Vậy `0,(5)- 0,0(8) = 7/15` hoặc `0,4(6)`  vì   `7/15 = 0,4(6)`
