Hi! Lets figure this out!
Decimal expansion, well one way to get the decimal for 7/22 is to simply divide, 7 by 22,
7 / 22 = 3.18181818, or 3.18 (with the .18 repeating)
Another way i have seen decimal expansion is to take the number and seperate it similar to the picture below the answer
However this is not to acquire the decimal.
So the correct answer would be 3.18181818
Hope I helped!
