Question

bobby's collection of sports cards has 3/10 baseball card and 39/100 football cards. the rest are soccer cards. what fraction of bobby's sport cards are baseball or football?

Answer 1

OK. The way the question is written, there are other possibilities, but it seems to me the simplest possibility is that Bobby has 100 sports cards. If 3/10 are baseball, that's 30. He has 39 football cards. So for baseball and football together it's 69 cards.

 

Don't you love the way they put soccer in there to try to throw you off? LOL
