Chelsie saves 1/5 of her allowance and spends 2/3 of her allowance at the mall. What fraction of her allowance remains?

1/5 + 2/3 = 3/15 + 10/15 = 13/15
15/15  13/15 = ?

1/5 and 2/3 fond the common denominator of 15 so it would change 1/5 to 3/15 and 2/3 to 10/15 you add the 3/15 and 10/15 and that equals 13/15 subtract 13/15 from 15/15 or 1 and the answer is 2/15.
