color(blue)("Using the shortcut method")
Convert the 7/22 into a decimal then multiply by 100
7/22xx100=31.8181bar(81)
Then stick a % on the end giving
7/22xx100=31.8181bar(81)%
Where the bar over the last 81 means that they repeat for ever.
You could round this so I chose 2 decimal places giving:
31.81 to 2 decimal places

The value of 22/7 used to be the old approximation to pi That was in the days when calculators we not available and fractions were the norm.

To ul("understand") why the shortcut works and why we put a % on the end see my example:
