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

Math  Ms. Sue, Tuesday, September 25, 2012 at 9:12pm
1/5 = 3/15
2/3 = 10/15
3/15 + 10/15 = 13/15
15/15  13/15 = ??

You want to know how much you have left after she's saved some and spent some.

Wouldn't you multiply the 5 by 3 and the 3 by 5 because you're getting common denominators instead of adding?
