Answer: 14 & 2/3
Work Shown
220/15 = (210 + 10)/15
220/15 = (210/15) + (10/15)
220/15 = 14 + (10/15)
220/15 = 14 + (2/3)
220/15 = 14 & 2/3
whole part = 14
fractional part = 2/3
A real world example: you have 220 cookies and 15 friends you want to share them with. Each friend would get 14 whole cookies. So far they would eat 14*15 = 210 cookies. There are 220-210 = 10 cookies remaining. This last group of 10 isn't enough to give every person a whole cookie. Instead they would get an additional 10/15 = 2/3 of a cookie.
In summary, each friend would get 14 & 2/3 cookies. In other words, 14 whole cookies and then 2/3 of an extra cookie.
If you used long division, then you should find that 220/15 = 14 remainder 10. The "remainder 10" part is the numerator of 10/15.
