7x97 is divisible by 7

              \frac{96k}{7}=0
             96k=7
              \frac{96k}{96} =  \frac{7}{96}
             k=  \frac{7}{96}

Do you speak tagalog MomGie? :/
Yes. But it takes time sometimes before I could express my thoughts in Tagalog fluently. Sorry, but I'd rather explain Math rules in English, and I hope you don't take this as arrogance. Please? :-)
