Answer:
\(\frac{7}{2}=0.318181818181818181818181818...\)
Step-by-step explanation:
The given number is
\(\frac{7}{22}\)
This is a rational number, because it's infinite and repeats a decimal pattern, as follows
\(\frac{7}{2}=0.318181818181818181818181818...\)
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 \(18\). So, the expansion of the number is expresses as the expression above.
