Answer:
[tex]\frac{7}{2}=0.318181818181818181818181818...[/tex]
Step-by-step explanation:
The given number is
[tex]\frac{7}{22}[/tex]
This is a rational number, because it's infinite and repeats a decimal pattern, as follows
[tex]\frac{7}{2}=0.318181818181818181818181818...[/tex]
The three suspensive points means that this number repeats the pattern until infinite, this type of numbers are called periodical number, and its periodicity is in this case [tex]18[/tex]. So, the expansion of the number is expresses as the expression above.
