Bobby's collection of sports coat has 3/10 facet baseball cards and 39/100 football cards. The rest are soccer cards. What fraction of Bobby,s sports cards are baseball or football cards?

Respuesta :

69/100 bc 3/10 * 10 = 30/100 and 30/100 + 39/100 = 69/100

69/100 because 3/10 is equal to 30/100 and when you add 30/100 plus 39/100 you get 69/100.
